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)	SRF3	11	+7.310s (6.60%)	+5.612s (5.01%)
Buttonwillow Raceway Park (2.92 mi)	SRF3	21	+5.345s (4.53%)	+2.843s (2.46%)
Buttonwillow Raceway Park (3.02 mi)	SRF3	5	+4.854s (4.15%)	+4.243s (3.64%)

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.
