Compare cars

Each number is the median of each driver’s last 10 runs, then the median across drivers. Spins, pit laps and caution laps are left out. A car shows once it has 3 clean laps at that pace; numbers are the median of every driver in the group. A number with fewer than 3 laps behind it stays blank.

A pace group compares drivers of similar speed: lap time as a % of the reference lap, the median of the fastest 10% of drivers in the class. 100% is about alien pace, 101% competitive, 102–103% good, 104–105% midpack, 106% tail-ender, 107%+ offline. The page opens on the signed-in driver’s own group, else on the group with the most drivers here.

The chart reads each clean lap: tire life at the end of the lap (the mean of the four corners), lap time and VE or fuel used, by lap on the tire set. The out-lap is lap 1 on a new set and is left out, so lines usually start at lap 2. A stint on a used set starts at the laps its tire life says it had. Each driver’s last 10 stints count; a point shows once 3 laps are behind it. The dotted tire life line after the last measured lap is a projection at the car’s median wear a lap from the table (else from its measured laps), out to lap 30 or 40% life. The chart and the table use the same class and pace group; the chart counts the drivers with per-lap data, so its driver count can be lower.

Wet conditions use the tire LMU calls for: slicks in Damp, wets from Slightly Wet on. Numbers refresh every 10 minutes. Group scheme after the Ohne Speed LMU lap-time sheet.
