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 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 ">" (with ">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

Sectors are numbered in lap order from start/finish, whatever each event's timing called them; the loop names are SCCA timing's.

the standard power and torque curve and will be ineligible for competition until power is corrected and the engine is sealed. The

The CRB reserves the right to implement a requirement that engines be submitted for dyno testing and sealing at any time. If
implemented, engine performance will be compared to known specimens. Engines will be denied a seal if they test above 102% of
the standard power and torque curve and will be ineligible for competition until power is corrected and the engine is sealed. The
participant will be responsible for all costs of dyno testing and delivery. This provision is included to dissuade the competitors
from exploiting the rules and expending funds to maximize performance of a budget-minded engine option."
