Pit strategy planner
Turn fuel range, tyre limits, pit loss, and race length into an explainable stint plan. Compare the baseline against a live extra-lap and higher-consumption stress test.
Race assumptions
Every input remains visible so the plan is explainable and repeatable.
Race laps
Whole laps
Average lap
Seconds, e.g. 100 = 1:40
Fuel per lap
Litres or consistent units
Tank capacity
Same fuel unit
Finish reserve
Fuel remaining at finish
Maximum tyre stint
Laps; 0 disables tyre limit
Base pit loss
Entry, stop and exit seconds
Tyre-change loss
Additional seconds per stop
Baseline plan
2
minimum stops under the entered fuel and tyre limits
Predicted laps

Stint timeline
Maximum-length opening stints
Stint 1
20 laps · 60.0 fuel
Stint 2
20 laps · 60.0 fuel
Stint 3
10 laps · 33.0 fuel
What this planner can decide
The planner finds a feasible minimum stop count and maximum-length opening stints under your fuel capacity, finish reserve, and tyre-stint limit. Estimated time adds the entered pit and tyre service loss. It does not invent tyre degradation, traffic, safety-car savings, refuelling flow, or mandatory-stop rules.
Timed races need a finish rule
Race length is predicted from average lap time. Enable the extra-lap switch only when the event can start another lap as time expires. In multiclass racing, the leader's pace may determine total race laps, so test both scenarios.
