Against the front of the class, by track and class

Track	Class	Sessions	Typical gap to class best	Closest
Buttonwillow Raceway Park (2.57 mi)	SM	5	+1.805s (1.48%)	+1.234s (1.01%)

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.
