Stint & strategy planner

Simulates a time-certain endurance race lap by lap: fuel stints, tyre life, pit-stop loss and where the windows fall.

A 7-stop is on the table — you'd need to average 2.43 L/lap (currently 2.60). Lift-and-coast into the braking zones to find the difference.

Model assumes constant fuel burn, linear tyre degradation, optimal fuel fill (no dead weight) and green-flag running throughout. Treat the lap count as ±1 and always carry a safety margin.
