BoP Lab / Buttonwillow Raceway Park
This track has been raced on 2 configurations (19, 2.92 mi; 3.02 mi). Laps on different configurations are not comparable, so only events on the 2.92 mile layout are shown; switch above to see the others.
SRF has no laps in the events chosen. It ran at Super Tour Apr 2017, Majors Apr 2016: add those events.
BSpc has no laps in the events chosen. It ran at Cal Club 2021: add that event.
Sectors are not comparable across all of these events. Sector times and the theoretical lap use Super Tour Apr 2018, Cal Club 2022 only. Super Tour Apr 2019 (sectors cut at different points) counts towards whole-lap times and trap speed only.

One row per driver and car (a driver who changed cars has a row for each). Each cell is that driver's best in that car across the selected events, with the session it was set in. Best 5-lap stint is the mean of the driver's quickest five consecutive race laps, and consistency is how far their median race lap sat behind their best in that race (small is a driver who does it every lap); both come from the race with the best stint. The fastest in each column is purple, and a car whose best lap is more than 115% of the fastest in its class is greyed (marked ">115%" beside the driver) and left out of the colour scale. Click a column to sort, a row to highlight it. Theoretical lap is the sum of the best sectors, whichever laps they came from, and never slower than the best lap (where a car's fastest laps were recorded without sector times, its best lap is used). The 115% mark is about the car's best lap only: a car whose best lap is within 115% of the fastest in its class is never marked. Greyed sectors with no theoretical lap mean the sector times on file do not add up to a believable lap. Letters refer to the events above; Q is qualifying, R a race.
Sectors
- S1 SF → IM1 1.00 mi
- S2 IM1 → IM3 1.00 mi
- S3 IM3 → SF 0.92 mi
- SPd IM2 → IM3 0.02 mi
Sectors are numbered in lap order from start/finish, whatever each event's timing called them; the loop names are SCCA timing's.
