Track map: sectors and speed trap

×

One run is left out as not that car's own laps (far quicker than the car managed in any other session and than anyone else in its class all week; usually a swapped transponder): Austin Hill in Runoffs 2021 Grp 4 Run 3 FA,FE2,FX,P1,P2 Sun (1:34.388; the car's best in any other session was 1:38.852 and the rest of the class's best all week 1:38.419).

One lap is left out as timing errors (far too short to be a lap of this track). The rest of those sessions, sectors included, is used.

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

• S1 SF → IM3 1.37 mi
• S2 IM3 → IM4 0.48 mi
• S3 IM4 → SF 0.75 mi
• SPd IM1 → IM2 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.

By car

The best any driver of each car managed across the selected events, with who set it. Spellings and model years of the same car are grouped; click a row marked ▸ to see each version. Grouping is worked out from the names, so tell us if two cars are wrongly merged or split.
