Every prediction below was produced during the race and validated against ground truth after. ML model validation — what the models saw vs. what actually happened.
Tire health over race
Each driver falls toward 0 through the stint and rises after a pit — back to 1.0 on a fresh set, or lower if the tire fitted already has laps on it. Pit events shown as vertical markers.
Tracks how much performance budget a tire has left on a 0–1 scale. Warns 3+ laps before the cliff that causes sudden lap-time loss — earlier than any broadcast graphic.
Algorithm
A Kalman-filter state-space model tracks each tyre's degradation trajectory lap by lap, calibrated per compound and circuit.
