F1 Pit Strategy

replay: sample streams the offline fixture; a numeric key such as 9904 replays a finished race from OpenF1. live: use latest to follow whatever session is running now. A stream follows one car; to watch both cars of a team, open a second tab — each stream decides on its own.

Decision

No decision yet

The engine fits a degradation curve per compound and needs at least 3 clean laps of the current compound before it can say anything. Out-laps and anomalous laps (safety car, standing start) are excluded from that count, so the first decision of a stint usually arrives on its third or fourth lap.
