Delta Tyre Strategist, a model for calling the race

Field notes

Delta describes a lap-time model that combines compound offset, tyre wear and cliff, fuel weight, warm-up and track temperature, then tests legal compound sequences with up to three dry stops or four in rain. Users can step through the resulting lap-by-lap simulation, alter stint tyres and pit laps, or replan for rain; the site says comparing against a real race uses public OpenF1 timing data.
