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.

Letters to Fastrack
STU Request for Mazda Renesis Engine Street Port
#26005 from Dale Shoemaker · Not recommended · Minutes (2019-03 Fastrack)
Thank you for your letter. The Renesis engine already has ports larger than the street port
template. There would be no reason to allow street porting specifically on a Renesis.
