Race (after the grid)Jorge Lorenzo · 32%Daniel Pedrosa · 5% · from P60.84 / 0.842.5 / 2.5

Error: average positions off, compared with the calibrated grid (the grid turned into expected positions with a simple regression, no model). If the model does not beat it, its edge over the raw grid is only calibration.

Official classification of each session (Dorna). Best lap and the tyres used on it: official FIM PDFs. Long-run pace: median of the clean laps in long runs (5 flying laps or more); blank if the rider did none. Every rider runs their own programme and fuel load, so long-run pace only compares within the same session.

Before the race

What to expect this weekend: race and qualifying outlook, the weight of the grid and the weather.

Who rules each sector

Finish line S1 S2 S3 S4 · 4,812 m per lap

Approximate sectors: estimated from the time spent in each sector (typical error 5 to 10% of a lap) until we have the official split points.

Fastest per sector: 2018–2026

Median gap to the fastest rider in each sector within each session, across all seasons at this circuit; active riders only. The name on the layout is the sector leader. Sector split points on the map are approximate.

A track for grid position, or an open one?

C15

An open track: the grid decides less here and there are more comebacks.

Grid ↔ result

When two teammates disagree between pace and grid, pace wins 50% of the time (between 22% and 79%; 8 cases).

Descriptive, over 6 races (2018–2025). 100 = the track where the grid matters most; 0 = the most open. Within a team, practice pace tells who will finish ahead 7 times in 10, but when the faster teammate qualifies behind, they finish behind 6 times in 10: grid position weighs more than pace.
