02Session summary
03Track map — who is fastest where
Segments coloured by the fastest team in each part of the lap. Numbered dots mark corner apexes. Click an apex to jump to its table row · hover a turn row to spotlight it on the map.
04Turn-by-turn analysis
Each corner window (±1.2% of lap distance around the apex) is ranked by average speed. Faster through the corner means better. Click a column header to sort.
05Head-to-head
Pick any two analyzed drivers: per-corner speed deltas across the whole lap, fought out on the duel map.

07Team analysis
08Sectors & speed traps
Sector splits and trap speeds from each driver's best lap (I1/I2 intermediates, ST finish-line trap).
09Race pace & tyre degradation
Stint-average pace and degradation slope (seconds lost per lap, least-squares fit). Out-laps and incident laps are excluded.

13How this works
Best lap. For every driver we take the single fastest non-pit-out lap of the session you selected — nothing else from the weekend is used.
Same point on track. Speed samples arrive over time, but drivers reach each point at different times. We integrate speed into distance travelled and resample every lap to 1,000 evenly spaced points, so point 500 is the same piece of asphalt for everyone.
Corners. Apex positions come from official circuit data fetched live. Each corner is a small window (±1.2% of lap distance) around its apex.
Ranking. Within each window we average each driver's speed. Highest average wins the corner. A team's score is the mean of its drivers. "Corners won" counts windows topped.
Tyres & sectors. Compounds come from the session's stint list matched to the lap number of each best lap; sectors and traps are the official splits of that same lap.
