Pace Mode
Which pace mode a driver is running — push, hold, manage, warm-up or delta — per lap.
How it works
A Gaussian mixture over the degradation-detrended pace residual quantises each lap into one of five named modes. The mixture is fitted per compound with a data-selected component count and then mapped onto the five product labels, so the mode boundaries follow the season's own pace distribution rather than fixed thresholds. Serve aggregates the per-mode posterior mass rather than reporting a hard assignment only.
Inputs
- degradation-detrended pace residual
- tyre compound
- stint lap
- fuel-corrected lap time
Output
Calibration
Gated on held-out log-likelihood gain over a null model, not on cluster compactness, with an age-confound control; both gates carry a negative control that fails them. See the calibration reference for the shared pipeline.
