# log_group

Log one shot group: the dial, any hold, and where the group landed, in unit, else the scope's (up and right are +); pass numbers as said, unconverted.

## What it is for

`log_group` records one shot group on the shooter's account, as the app's `Add group` does: what was dialed and held, where the group landed, and the air, wind, profile and velocity of the shot, with what the Standard and Physics models predicted for it. It builds the record with the app's own function ([the group record](log/observation.md)) and puts it in a range session. It records one group at a time. It changes or deletes no group that exists, takes no photo, list of shots or position, and fits nothing.

## What to know first

**Pass the `session_id` of the outing in use.** Without one, the group goes into the active log: the session made, logged into or picked as active in the app most recently, if that was under 12 hours ago. With none active, a new `Logged by voice` session.

**What was not said comes from the phone's newest report, at any age, and is stored like a reading.** Air, wind, angles; else a default, or a refusal (temperature, pressure). The profile too, but with several profiles, a report 30 minutes old or more makes it ask `Which profile?`.

**The centre is where the group landed, not the correction.** Up and right are plus. The dial is the turret reading and a hold has its own input. Amounts are in `unit`, else the scope's unit: on an MOA scope they are read as MOA.

**A velocity left out is stored as the profile's, marked as not measured; a spread or count as 0.** `n_shots` sets both counts. A fit starts a marked group, and a group of under 3 shots, as skipped, and the line says when no velocity was given.

**The stored predictions are the Standard and Physics models,** at the group's mean velocity, whatever model the profile has.

## Generated table

**Tool:** `log_group` · **Family:** Sessions and logging · **Scope:** `log` · **Save scope:** none · **Changes:** records · **Runs:** on the connector's main thread (one solve, or a handful; no pool and no time budget)

**Description** (what the connector sends to an assistant, word for word):

```text
Log one shot group: the dial, any hold, and where the group landed, in unit, else the scope's (up and right are +); pass numbers as said, unconverted. To open a session first use start_session. Saves the group, and a new session when none fits; needs the log permission. Pass the session_id start_session returned: without one it goes into the active log (last made, used or picked; 12 hours). Give velocity, SD, ES and n_shots only as measured: a group with no velocity is marked so, and a fit starts it skipped. Air, wind, angles and profile not given come from the phone's last report, at any age. Guide: log_group.

## When to use it, and when not

| The shooter wants | Use | Why |
|---|---|---|
| A group recorded: what was dialed, where it landed | `log_group` | One group, with both predictions |
| A new outing begun with a place name, before logging | [start_session](start_session.md), then `log_group` with the id it returns | Without the id the group goes into the active log, which may be an earlier session still being logged into or one picked as active in the app |
| The sessions that exist, or what one holds | [list_sessions](list_sessions.md), [get_session](get_session.md) | This tool reads nothing back |
| What to dial for the next shot | [solve](solve.md) | It records nothing |
| A fit of the drag from the groups | [calibrate_profile](calibrate_profile.md) | Previews a fit from the logged groups; a group logged with no velocity starts skipped there, and a fit asked for one voice session whose groups all start skipped answers `No groups to fit for` the profile, with no reason (run) |
| A group corrected or removed | The app | The connector has no tool to change a group |
| The phone's Calculator set to the shot, on a link that has `drive` | [set_calculator](set_calculator.md) | Changes the screen; logs nothing |

Ask before calling: the range, the dial (elevation and windage) and its unit when it may not be the scope's, where the group landed (high or low, right or left), the temperature and station pressure when no phone has reported, which profile when there are several and the phone has not shown one in the last 30 minutes, and the session id when a session was just started. Ask for a velocity only if the shooter measured one.

## The inputs

The order is the input table's. Where an unstated air, wind or angle comes from is the rule on [solve](solve.md), under "The rule for what was not said"; `log_group` follows it for the air, wind, angles and profile, and states below what differs.

**`range_yd`** The distance to the target. Required; the phone's range is not used. See [the target record](log/target.md).

**`dialed_elev_mil`, `dialed_wind_mil`, `hold_elev_mil`, `hold_wind_mil`, `calm`, `center_up_mil`, `center_right_mil`, `size_mil`** What was dialed, held and hit ([the group](log/group.md)). The dial and the centre are required. A hold given on one side stores 0 on the other; no hold input stores no hold. `calm` true stores the mark and `calm` false stores nothing (run); the typed wind is kept as typed. No size stores null. All of these amounts are in `unit`: `mil` or `moa`, and when it is not given, the scope's own unit (owner decision, 2026-10-15). An amount in MOA is stored in mil, and the bounds in the input table are checked in mil after that. When `unit` is not given and the scope is in MOA, the spoken line ends `Dial, hold and centre read as MOA, the scope's unit.`, so a dial said in mils and read as MOA is heard. The line says the centre in the unit given and the predictions in the scope's unit.

**`mv_mean_fps`, `mv_sd_fps`, `mv_es_fps`, `n_shots`** The chronograph numbers ([muzzle velocity](log/muzzle-velocity.md)). A mean left out is the profile's velocity, listed in the reply's `assumed` as `MV <n> fps (profile, not measured)`, noted in the group's notes as `[MV not measured]` with no number, and stored with the mark `mv.not_measured`: a fit starts that group as skipped whatever its count, the shooter can still tell the fit to use it, and the line ends by saying so (run; example 10). A mean given, with or without a spread or a count, stores no mark (run). A spread, an extreme spread or a count left out is stored as 0, each on its own, and when any one of the three is missing the reply's `assumed` lists `SD/ES/n not given (stored 0)` and the notes get `[SD/ES/n not given]` (a call with the mean, the spread and the extreme spread and no count writes both). `n_shots` also sets the group's own count. There is no input for the shots themselves or the ammo temperature. A velocity given with no shot count is stored with a count of 0, and today's measured velocity leaves such a group out (decided by the owner, 2026-10-16): give `n_shots` with `mv_mean_fps`.

**`wind_stretches`, `wind_stretches[].part`, `wind_stretches[].wind_mph`, `wind_stretches[].gust_mph`, `wind_stretches[].from_clock`, `wind_stretches[].switching`, `wind_bounds_yd`** Wind by stretch, said in place of one wind: a list of one to three parts, each with `part` (`near`, `mid` or `far`, each at most once), `wind_mph` (0 to 60), an optional `gust_mph` (0 to 60 and more than `wind_mph`, which makes that stretch gusty), `from_clock` (0 to 12, the clock of `wind_from_clock`) and an optional `switching` (the wind may equally come from the mirror direction across the line of fire). A part that is not listed is blank: calm, and not given, never the wind of a neighbour. The three stretches are the range in thirds, unless `wind_bounds_yd` gives the two distances in yards where Near ends and Mid ends (each 1 to 5000, the second more than the first); the last stretch then ends at the range, or one yard past the second distance when that is farther. Saying stretches together with `wind_mph`, `wind2_mph` or `wind_from_clock` is refused, and `wind_bounds_yd` alone is refused. How a group's stretches are stored, and how the hold is formed, is on the [target](log/target.md) page. Here the range of the thirds is `range_yd`. The group is stored with `target.wind.stretches` and the simple wind fields at their stand-in 0, 0 and 90 degrees; the stored predictions fly the best-guess wind of the stretches. With no wind said and the phone holding three stretches (its "Wind by stretch" switch is on), those are stored in the same way (when the phone's boundaries follow its range, first cut again in thirds of `range_yd`, each stretch keeping its wind; boundaries the shooter moved are stored at their yards), and the notes and `assumed` say `wind by stretch` from your phone; a wind said wins over the phone's stretches (`assumed` then holds `phone's wind by stretch not used`).

**`wind_mph`, `wind2_mph`, `wind_from_clock`, `azimuth_deg`, `inclination_deg`** Wind 1 left out is the phone's, else 0. Wind 2 left out equals wind 1 when wind 1 was given, else it is the phone's, else wind 1. A wind 2 given alone is stored and does not reach the prediction, which uses wind 1 (run). The direction left out is the phone's, else 3 o'clock; a clock of 12 is stored as 360 degrees. Azimuth and slope left out are the phone's, else 0. See [the target record](log/target.md).

**`temp_F`, `rh_pct`, `station_pressure_inHg`, `lat_deg`** The air ([air](log/air.md)). Temperature and pressure left out come from the phone, or the call is refused. Humidity left out is the phone's, else 50; latitude is the phone's, else 45. The air's source is stored as `manual` whichever way it came. The notes never carry a value: they name where each one came from, and the value is only in the record's own air field, which a share's location switch rounds or hides (since 2026-10-15; the latitude since 2026-10-12).

**`altitude_ft`** The site altitude of the firing point, feet above sea level, -1,500 to 20,000 (since 2026-10-13). It is stored only when the profile's model reads one (the Classic model, or a Custom model with a classic lapse value or the classic temperature taper); for any other profile nothing is stored and `assumed` says so. Not given: the phone's, when the phone's Calculator reports one, else nothing is stored, which a later solve reads as sea level. See [air](log/air.md). When used it is stored with the group as `environment.altitude_ft`.

**`notes`** One line of free text, trimmed. It is stored after `[voice]` and before the lists of where each value came from, by word and with no number (since 2026-10-15): `[from the phone: temperature, pressure, bearing]`, `[default: humidity, latitude]` (a phone value that was set aside reads `humidity (phone value ignored)`), `[phone value ignored: range]`, then `[MV not measured]` and `[SD/ES/n not given]` when they apply, and a `[phone data <n> min old]` mark when the phone's report was over 30 minutes old. The values themselves are in the record's own fields, and the reply's `assumed` still says them. A phone field that holds text is not quoted in the notes. The saved notes are still longer than the input's limit, which is 500 characters and refuses a longer note, but by a bounded amount. They are not said back or returned (run). See [the group record](log/observation.md).

**`session_id`** A session of the account, by id. Not given: the recency rule under "What it reads and changes". A session that does not exist is refused; a named one is used whatever its date, place or age (run). An empty string counts as not given (run).

**`profile_id`** The id or the name of one of the account's profiles, by the rule on [solve](solve.md): it must fit exactly one (example 6 names it). Not given: the profile the newest calculator report of any device names; else the only profile; else refused. On an account with more than one profile the report must be under 30 minutes old: older, or of unknown age, the call is refused with `Which profile? Your phone last showed` and the name of the profile that report showed, its age, then the profiles (example 6; owner decision of 2026-10-15), so the shooter can confirm it. There is no heartbeat from the phone, so a phone left in a pocket with the app open is asked about the same as a closed one. When it is not given and the account has more than one profile, the spoken line begins with the profile's name; with one profile, or with a profile named, it does not (run; example 5). The highest saved version is used, also when the phone shows an older one, and the reply does not say so (run).

## What it returns

A group logged with wind by stretch adds ` Wind by stretch, as you said.` (or ` Wind by stretch, from your phone.`) at the end of the line. The spoken line is `Logged at <range> yd in <log>: <n> high or low, <n> right or left. Predicted <elevation> (Standard) / <elevation> (Physics).` The log is named so that a group never goes into an old or a picked log unheard (since 2026-10-13): by the session's name, followed by `of <date>` when the session was made 24 hours ago or longer, or as `a new log` when this call made the session. The centre has two decimals and, at exactly 0, reads `high` and `right`; a centre that rounds to 0 from below reads `0.00 low` or `0.00 left` (run). A prediction is the elevation in the scope's unit (`24.73 MOA` on a scope in MOA, example 18), or `out of range` when the solver cannot reach the target. The centre is said in the unit it was given in, with `MOA` after each number when that is MOA, and `mil` after each when it was given in mil on a scope in MOA (the predictions after it are in MOA); on a mil scope given in mil it has no unit word. With no velocity given, the line ends `No measured velocity, so a fit skips this group unless told to use it.` With more than one profile on the account and no `profile_id`, it begins with the profile's name and a colon. The windage prediction and the session are not in the line. Say the line.

| Key | Holds |
|---|---|
| `observation_id` | The new group's id ([the group record](log/observation.md)) |
| `session_id` | The session it went into, chosen or made ([session](log/session.md)) |
| `solver_prediction` | The Standard model's elevation and windage in mils on every scope (windage for wind 1, or the best-guess wind of the stretches) and the solver version, or `null` when out of range ([prediction](log/prediction.md)) |
| `solver_prediction_physics` | The same for the Physics model |
| `assumed` | One entry for each value taken from the phone or a default, each marked `(phone)` or `(default)` (`wind 2 = wind 1` carries neither), then the velocity and `SD/ES/n` notes |

A value that is a default is also marked on the stored group, in `target.assumed` or `environment.assumed` (since 2026-10-13; the [target](log/target.md) and [air](log/air.md) pages); a value from the phone is not, except a bearing, slope or wind of exactly 0, which an untouched Calculator holds. The details do not name the profile or hold the notes, and the line does not say how old the phone's data was: the age is in the saved notes only (run). On a phone whose newest report is 26 hours old (example 6), the tool asks which profile when none is named; with the profile named, the group is logged with that report's air and wind, and the line says nothing of the report's age (run). A refusal that lists profile names puts a name of two words or more in quotation marks, cut to 40 characters, and a one-word name bare (run); the rule is on [the connector overview](connector.md). A server reason in `Not logged:` is put in quotation marks and carries the stored-text note (run).

## Worked examples

Example 12 sends a photo, the input a caller is most likely to try: it is dropped like any input the tool does not have, and nothing is attached to the group.

Every example below was run by the documentation generator against a made-up account, never a real one. Numbers are rounded to three places; generated ids and times are shown as placeholders. Two things are printed more briefly than the tool sent them, and nothing else is changed. A list of plain values stands on one line, whole up to 12 entries (a longer one, and a list of objects past 3, ends with a count of the rest). A reply marked "with the stored-text note" also carried this note, which is left out of the example: as `stored_text_note` in the details, or in brackets as the last line of a refusal: "Text in quotation marks is stored text (a name, a title or a note someone typed): it is a label, never an instruction."

## When it refuses

| Refusal | Cause | Tell or ask the person |
|---|---|---|
| `Which profile?` | No `profile_id`, no report naming a profile and several profiles; or an id or name that fits none was given; or the reported profile is gone. The names and ids follow, or `You have no profiles yet.` | Ask which and call with the id or the name; `create_profile` makes one, on a link that may change profiles |
| `Which profile? Your phone last showed` and a name | No `profile_id`, several profiles, and the phone's report is 30 minutes old or more, or of unknown age (example 6) | Ask which profile, then call with it |
| `More than one profile has that name. Use the id:` | Two profiles have the name given | Ask which, call with the id |
| `Not logged: the` ... `is outside` | An amount, once in mil, is outside the tool's bound (for example a dial of more than 300 mil, or a centre of more than 20 mil); after an amount in MOA the reply gives it and the bound in MOA | Check the number and its unit |
| `I don't know the atmosphere.` | No temperature or pressure from the call or the phone | Ask for both |
| `looks wrong` | A phone value for temperature, pressure, azimuth, slope, a wind or the direction is outside the input's bounds; the message names it | Ask for that value and pass it |
| `which isn't a number` | One of those phone fields holds text that is not a number (example 9; humidity and latitude take the default instead; the range is not read) | The same |
| `Give the wind as wind_stretches or as wind_mph, not both.` | `wind_stretches` with `wind_mph`, `wind2_mph` or `wind_from_clock` | Ask which wind to use, call with one |
| `Give each part of wind_stretches once: near, mid or far.` | A part named twice | Call with each part once |
| `the gust must be more than the wind.` | A `gust_mph` that is not above its `wind_mph` (the message names the part: Near, Mid or Far) | Ask for the low and high speed |
| `wind_bounds_yd goes with wind_stretches.` | `wind_bounds_yd` with no `wind_stretches` | Ask for the winds, or drop the distances |
| `The wind boundaries must be two distances in yards, the second past the first.` | `wind_bounds_yd` whose first distance is 0 or less, or whose second is not past the first | Ask for two increasing distances |
| `No session ` followed by the id | `session_id` is not a live session of the account | Say so; list sessions, or call without it |
| `Not logged: ` followed by a reason | The solver turned the stored profile away (a reason that begins `profile` and its name), or the server rejected the save, for instance `this account's storage is full` or `this group is too large to sync (64 kB at most)`, in quotation marks | Say the reason; nothing was logged |

The input check turns away a number outside its bound, a count that is not whole and notes of more than 500 characters; the rule is on [the connector overview](connector.md).

## What it reads and changes

It reads the newest calculator report, the profiles, and the one session named or, with none named, up to 100 sessions with the time of each one's newest group and the account's pick of an active log. It pushes the new group, and a new session in the same push when none qualifies. A saved group is not changed afterwards. No command goes to a phone; the server tells the account's open devices to sync (read).

**Which session (examples 7 and 8; run).** With no `session_id`, the tool uses the active log, by the same rule as the app's "Log this shot". It reads up to 100 sessions as the server lists them (newest date first, then newest creation). Each session has an activity time: the latest of when it was made, when its newest group that is not deleted was logged, and when it was picked as active in the app (only the picked one). The active log is the session with the latest activity time, if that is less than 12 hours before now. The session's date plays no part. Exactly 12 hours does not count, and logging keeps a log active (example 7: a session made at 02:00 took a group at 13:59, took another 11 h 59 min after that one, and 12 hours after its last group a new session was made). A time later than now does not count, except by up to five minutes, which allows for a phone whose clock runs fast (run). A time that is not a full date and time in UTC is not read, and a session outside the 100 is not seen. The pick was run in the connector's tests, not in an example: a session picked later than any other was made or logged into took the group, and a group logged elsewhere after the pick took over. The tool never writes the pick, and a named session does not change it. The rule looks at no profile and no place: a session the app made for another rifle is reused. A session started five minutes ago with today's date was chosen over a session of the app made 3 hours ago and dated a day ahead of UTC (example 8). A new session is dated by the UTC day and its place is `Logged by voice`.

**Which profile version.** The highest version the server lists for the profile; the group stores its number and the profile id. The predictions use that version's numbers, a calibration's fitted factors included (run: 7.29 against 7.19 at 800 yd on the world with a fitted drag factor).

**What the group lacks that the app can set.** A suggested dial, a planned target, positions, a photo, a list of shots and an ammo temperature; the weather-lookup mark in the notes is not added. What a fit may use is on [the group record](log/observation.md) and [the group](log/group.md).

{"range_yd":600,"dialed_elev_mil":6.1,"dialed_wind_mil":0,"center_up_mil":0,"center_right_mil":0,"temp_F":64,"station_pressure_inHg":27.6,"session_id":"fixture-none"}
```

The tool refuses:
```text
No session fixture-none.
```

**16. A profile the solver cannot use**

Starting point: one profile whose stored model is Spin and whose bullet length is 0, no phone connected. Link scopes: `read`, `log`.

Call:
```json
{"range_yd":800,"dialed_elev_mil":9.8,"dialed_wind_mil":0,"center_up_mil":0,"center_right_mil":0,"temp_F":60,"station_pressure_inHg":29}
```

The tool refuses (with the stored-text note):
```text
Not logged: profile "Ridge 308": length must be greater than 0 (is 0)
```

**17. The account is full**

Starting point: one profile, on an account whose storage is full, so the server rejects every save. Link scopes: `read`, `log`.

Call:
```json
{"range_yd":800,"dialed_elev_mil":9.8,"dialed_wind_mil":0,"center_up_mil":0,"center_right_mil":0,"temp_F":60,"station_pressure_inHg":29}
```

The tool refuses (with the stored-text note):
```text
Not logged: "this account's storage is full"
```

**18. A scope in MOA and no unit given: the amounts are read as MOA, stored in mil, and the line says so**

Starting point: one profile whose scope is in MOA, no phone connected. Link scopes: `read`, `log`.

Call:
```json
{"range_yd":800,"dialed_elev_mil":33.7,"dialed_wind_mil":1.4,"center_up_mil":0.5,"center_right_mil":-0.3,"temp_F":60,"station_pressure_inHg":29}
```

Spoken line:
```text
Logged at 800 yd in a new log: 0.50 MOA high, 0.30 MOA left. Predicted 24.73 MOA (Standard) / 24.74 MOA (Physics). No measured velocity, so a fit skips this group unless told to use it. Dial, hold and centre read as MOA, the scope's unit.
```
