int_driver_season_ratings - Off The Pace • docs

Part of the Skill family.

One row per (driver_id, season). Aggregates race residuals to season grain. Shrunk toward season league average (Bayesian, prior = 5 virtual races). Negative = faster than season average. Intermediate for era_normalized_driver_rating. Isolates driver strength from era variation (e.g., 2016 vs 2022 regulations).
