Timetable View Help

The main timetable page is a live, read-only view that any official can open on their own device. It shows the full day's schedule alongside predicted times that update as the ops clerk enters actuals. The page refreshes automatically every 30 seconds — no action required.

Header & Status Bar

Header bar

• Event name — The meeting name, circuit, and layout.
• GFL / Grid minutes — The formation lap duration and grid assembly time in use for this event, shown for reference.
• Live clock — Current time, updated every second.

Status bar

• Variance pill — Shows overall running variance: how many minutes ahead or behind schedule the day is running, based on the last session with a known predicted start. Green = on time or within a few minutes; amber = moderately late; red = significantly late; blue = running early.
• Curfew pill — Shows the curfew time and a countdown. Turns amber when within 30 minutes; turns red when curfew is passed.

Timetable Columns

Columns are grouped by colour band across the header. Here is what each group and column contains:

Identity columns

Column	Meaning
#	Session number for the day. Break/lunch rows are not numbered.
Series	The racing series or championship name.
Session	Session type and number — e.g. FP1, Q1, Race 2.
Badges	Badges indicating session format: S (standing start), R (rolling start), GFL (formation lap planned), Pit (pit stops permitted), SC (safety car format), LS (live snatch start — licensed venues only).

Scheduled group

The original planned timetable as entered in Setup. These values never change during the event.

Column	Meaning
Dur	Planned session duration in minutes (race/session only, excludes formation lap).
Start	Planned session start time.
Finish	Planned finish time (start + duration).
Tidy	Scheduled turnaround gap between this session's planned finish and the next session's planned start.

Override group

Values entered by the ops clerk to adjust predictions without altering the original schedule. Blank when no override is in effect.

Column	Meaning
Dur	Duration override in minutes. When set, this replaces the scheduled duration for all predicted finish time calculations.
Tidy	Tidy-time override in minutes. When set, this replaces the scheduled turnaround gap when cascading predictions to the next session.

Actual group

Times recorded by the ops clerk as the event progresses. Bold text in the Predicted columns indicates that an actual time has anchored the prediction.

Column	Meaning
Grid	Actual time cars were released from pit lane to the assembly grid (race sessions). For reference and record-keeping.
GFL	Actual time the green flag was shown / formation lap began (sessions with a planned formation lap only).
Start	Actual session start time — lights out (standing start) or rolling-start trigger.
Finish	Actual time the chequered flag was shown.

Advised group

Calculated call times for race sessions, derived from the predicted start time. Blank for practice, qualifying, and breaks.

Column	Meaning
Grid	Advised time to release cars from pit lane to the assembly grid (= predicted race start − GFL minutes − grid minutes).
GFL	Advised formation lap start time (= predicted race start − GFL minutes). Only shown for sessions with a planned formation lap.

Predicted group

Column	Meaning
Start	Predicted session start time. Bold if anchored by an actual start time. Shown in colour if it differs from the scheduled start.
Finish	Predicted session finish time. Bold if anchored by an actual finish time. Shaded amber or red when close to or past curfew.

Gap group

Column	Meaning
↑↓	Variance — how many minutes ahead (−) or behind (+) schedule this session is predicted to start, compared to its planned start time.
Slip	The actual tidy time achieved between the previous session's finish and this session's predicted start.
Diff	Slip minus the scheduled tidy time. Positive = the turnaround took longer than planned; negative = it was quicker.

How Predictions Work

Predicted times cascade forward through the timetable from the last known actual. The rules are straightforward:

1. If a session has an actual start time, its predicted start is that actual time.
2. If a session has an actual GFL time (and a formation lap is planned), the predicted start is the GFL time + GFL minutes.
3. Otherwise, the predicted start = previous session's predicted finish + effective tidy time.
4. If a session has an actual finish time, its predicted finish is that actual time. Otherwise it is predicted start + effective duration.

Effective duration = duration override if one is set, otherwise the scheduled duration.
Effective tidy time = the tidy override on the previous session if one is set, otherwise the scheduled gap between the two sessions.

Cancelled sessions are skipped in the cascade — the time slot is effectively removed, but the turnaround gap after the cancelled session is preserved for the following session.

Colour Coding

Variance column (↑↓)

For upcoming and active sessions only (completed sessions are not highlighted):

• Running late up to 15 min — green background.
• Running 15–20 min late — amber background.
• Running more than 20 min late — red background.
• Running early up to 15 min — bold green text, no background.
• Running 15–20 min early — bold amber text.
• Running more than 20 min early — bold red text.

Predicted Finish column

• Within 20 minutes of curfew — amber background, deepening to red as curfew approaches.
• At or past curfew — red background.

Row states

• Completed sessions are shown in muted grey text to visually recede from upcoming sessions.
• Active sessions have a green left-border accent.
• Cancelled sessions are shown in muted text with a strikethrough.
• Red-flagged sessions have a red background.

Session Status

Each session shows a status chip in the Status column:

Status	Meaning
Pending	Session has not yet started.
GFL	Formation lap in progress (actual GFL time recorded, no start time yet).
Active	Session is running (actual start time recorded, no finish time yet).
Done	Session is complete (actual finish time recorded).
Red Flag	Session has been stopped. Manually set by the ops clerk.
Cancelled	Session will not run. Removed from the time cascade.

Auto-Refresh

The timetable page reloads data from the server every 30 seconds automatically. The footer shows the time of the last successful refresh and a countdown to the next one. No action is needed — simply leave the page open.

Multiple officials can open the same URL simultaneously on their own devices (phones, tablets, laptops). All will see the same live data. Share the URL in the format https://your-server/?event=N where N is the event ID visible in the address bar when the event is selected.
