What it shows
The leaderboard is built from the driver-skill residual of the seven-term identity:- Equal car: each lap is decomposed into fuel, tyre compound, rubber, ambient, constructor, and driver-skill components. The board uses only the driver-skill residual the part left once car and conditions are removed so a slow car no longer hides a fast driver. Negative = faster than the field.
- Split by era, not blended: records are computed separately for 2018–2021 (last-gen aero) and 2022–2024 (ground-effect), split on the 2022 regulation change. Pace is only ever compared within one car era.
- No single year: every race a driver ran at the circuit within the era is pooled, so this is a multi-season record.
- Shrunk toward the driver’s own average: a one-race sample is regularised toward the driver’s era-wide mean (Bayesian, prior = 5 virtual races). The Conf. column is the data fraction
n / (n + 5); values below 0.3 (amber) are prior-dominated. - 95% CI: overlapping intervals mean two drivers are statistically tied at that track.
- Min. races: filters thin samples; the gap-to-leader is measured against the fastest driver shown.
This is a statistical reconstruction of equal-car pace, not a physics simulation. Read the ranking as expected-value estimates, with the confidence and CI columns as the uncertainty.
How to use it
- Select a circuit and era from the filter bar; the leaderboard loads.
- Read the ranking as track-specific driver skill, car removed.
- Check the Conf. column amber (< 0.3) rows are mostly prior and mean “not enough races yet”.
- Compare CIs before ranking two rows overlapping intervals are a tie.
Reading the signal correctly
The board is within one era and one circuit by design never average a driver across the 2022 boundary, and don’t read it as an all-time ranking. The skill residual is what survives car removal, so a midfield driver can top a circuit where they consistently over-delivered.Data source
The chart queriesint_driver_circuit_era_affinity, built on the driver-skill residual of fct_lap_residuals, via DuckDB-Wasm in the browser.
The data window covers 2018–2024, split at the 2022 regulation change.
