Changes in the middle of a race

Race day never goes exactly to plan. This page holds the rules for what Trusty Track does when it changes underneath you — a late arrival, a withdrawal, a dead lane, a skipped heat, a wrong time.

One pattern covers the first three. What happens to a round depends on how far it has got:

The round	What happens
Not started	Rebuilt to match the new situation — nothing is at risk, so everybody gets an equal schedule
Part-way through	Every recorded heat is kept. Only the heats still to come change
Finished	Left alone

A late arrival

Add the racer to the roster and check them in. Checking them in is what puts them in the racing — there is nothing else to press.

A round that has not started is rebuilt with them in it.
A round part-way through keeps every recorded heat, and new heats are added at the end so the newcomer gets one turn in each lane — the same spread everybody else got.
A finished round is left alone; they join from the next round.

The added heats need other cars in their lanes, so a few racers run once more than their peers. A timed race shrugs that off; a points race sets that round aside and the Standings page says so. Two children arriving together share their extra heats rather than each pulling in a separate set of veterans.

In a Balanced or Elimination round, a latecomer simply joins the next set of heats — on a clean record in elimination, and never a race that is already decided.
A championship round is never joined directly: a latecomer qualifies for it by racing.
No heats against a checked-in racer on the roster means they arrived after the round they would have been in had finished. They will be in the next round created.

A withdrawal

Open the racer's check-in entry and turn Passed Inspection / Checked In off.

A round that has not started is rebuilt without them.
A round part-way through keeps every recorded heat; their lanes in the remaining heats are emptied. Nobody else's schedule changes, and nothing is set aside — an empty lane gives nobody extra heats.
A finished round keeps their results.
A championship spot they held in an unraced round goes to the next qualifier.

If it was a mistake, check them back in — they get their place back the same way a latecomer does.

A lane stops working

Settings → Tracks → Lanes in service — untick the lane. It applies the moment you click it, not when you press Save, because a lane dies mid-event rather than by appointment.

Every round generated from then on is scheduled around it: the remaining lanes are used, everybody still races the same number of times, and heats name the lanes that actually exist rather than renumbering them.
A round already under way follows the table above: recorded heats keep their results, and the dead lane is dropped from the heats still to come. The cars that lose a heat this way make the round set aside in a points race.
Tick the lane again when it is fixed and the next round uses it. A track with no working lanes generates no schedule at all, and the settings page says so.

Turning down a track's lane count

Settings → Tracks → Lanes — lowering the number and pressing Save Settings is brought into line the same way a lane going out of service is, following the same table above: a round nobody has raced is rebuilt for the lanes that remain, a round part-way through keeps its recorded heats and has the lane it no longer has dropped from what is still to come (set aside in a points race, same as above), and a finished round is untouched.

Skipping a heat

Skip Heat passes over the current heat without racing it — for when every car in it has scratched.

The schedule moves on. A skipped heat holds nothing up: the round still finishes, and a championship round waiting on it still fills.
It can be raced later with Run if the cars turn up after all.
In a points race its cars are scored as last in it; in a timed race it is simply not part of anyone's average. See Scoring.
In an elimination round a skipped heat is neither a win nor a loss for anyone.

A wrong result

Edit on a recorded heat corrects individual times.
Re-Run clears the whole heat so it can race again.
Either way, who advances is re-decided from the corrected results.
If the schedule changes while a heat is armed on the timer — a rebuild, a reorder, a deleted round — the timer disarms itself and says so, rather than recording times against cars that have moved. Re-arm the heat and run it again.
