FB + F500 + SRF + BSpc at Buttonwillow Raceway Park
This track has been raced on 2 configurations (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.
BSpc has no laps in the events chosen. It ran at Super Tour Feb 2021: add that event.
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. The columns are about the car: its best lap, the lap its best sectors add up to, its sector times and trap speed. "Driver metrics" adds two about the driver: the best 5-lap stint (mean of the quickest five consecutive race laps) and consistency (how far the median race lap sat behind the best in that race; small is a driver who does it every lap), both 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.
