Against the front of the class, by track and class

Track	Class	Sessions	Typical gap to class best	Closest
Virginia International Raceway (3.27 mi)	HP	4	+17.497s (12.98%)	+15.846s (11.73%)
Unknown track (3.27 mi)	HP	2	+14.857s (9.77%)	+14.857s (9.77%)

Gap is the driver's best lap in a session against the fastest lap in their class in that same session (zero is fastest in class), shown as time lost and as a share of the lap, so conditions cancel out and tracks can be compared. Typical is the median session.
