Against the front of the class, by track and class

Track	Class	Sessions	Typical gap to class best	Closest
Indianapolis Motor Speedway (2.59 mi)	STU	6	+7.678s (7.15%)	+7.265s (6.74%)

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.
