About this data
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.

As printed in Fastrack

This AS Spec Lines re-organization simplifies the Spec Lines for all drivers. This version gives the chassis information on what
engines can be put in their cars. It removes information that is now repeated in the ruleset and adds engine/weight combos as
well as wheelbase/tire size information. The Notes in the Spec Lines have been reviewed to remove information now listed in
the engine build sheets and retain information pertinent to the chassis selected. Where there is nothing in the notes, it is not an
error. It just means everything a driver needs is now in the main rules or the build sheets.
