Pit wall strategy lab

Change the call. Replay the race.

Choose a Grand Prix, edit a driver's pit strategy, and see whether the alternate call would gain time, lose time, or get trapped in traffic.

Awaiting pit wall call

Run a structured strategy or ask the optimizer to produce the first alternate-strategy overlay.

Model Lab

Selected engine

No engine selected

Model Lab shows both available simulator paths. Auto mode compares their validation scores and uses the engine that reconstructs the real race most reliably.

AI can parse strategy text and write narration, but the simulator owns every lap time, gap, position, confidence score, and optimizer choice.

Baseline engine

OLS pace model plus ghost-field replay

Waiting

Fits trusted clean laps with a regression, then replays one driver's alternate strategy against real-race ghost cars.

  • Predicts lap time from driver pace, tyre compound, tyre age, fuel burn, and pit loss.
  • Keeps the rest of the field anchored to the real race.
  • Useful as the conservative fallback when advanced validation is not better.

Advanced engine

Calibrated full-field simulation

Waiting

Starts from baseline, then adds historical priors, nonlinear tyre phases, residual offsets, calibration, and full-field interaction.

  • Models evolving gaps, traffic trains, pit events, and deterministic overtakes.
  • Replays the actual race first to learn capped race-specific corrections.
  • Only wins auto-selection when validation says it reconstructs the race better.

Final error checks finishing order, trace error checks lap-by-lap position shape, and the score combines those with bounded gap and event-plausibility penalties.

Quick terms

F1 Glossary

Pit stop

A tyre change. It costs time now, but fresher tyres may be faster later.

Compound

Tyre type: soft is quicker but wears faster; hard is slower but lasts longer.

Stint

The laps between pit stops on one set of tyres.

Dirty air

Time lost when following another car closely and unable to pass.
