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
EP Nissan 350Z E Prod query
#38765 from David Muramoto · Not recommended · Minutes (2025-09 Fastrack)
Thank you for your inquiry, however, the 350Z is beyond the performance level of EP, therefore its classification is not
recommended.
2025 Runoffs Proposal Feedback
#36354 from David Muramoto · No action required · Minutes (2024-11 Fastrack)
Thank you for your letter. The shortened event will achieve savings in lodging, meals, and time away from home/work. It also
helps in staffing the event. Testing revenue helps to offset the costs of Runoffs for all and, but for that revenue entry fees
would be significantly higher. As you note the program does not and was not intended to impact Regionals which are separate
and distinct from Majors/HST. Those are intended to be focused upon the local demands. Prior to introduction of the Major's
program the sole path to Runoffs was though National events. We appreciate your continued support of SCCA's Road Racing
Program and hope to see you on the grid in 2025.
