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

T3 Mustang EcoBoost

#32501 from Jim Leithauser · No action required · Minutes (2022-04 Fastrack)

Thank you for your letter. The ad promotes the car as something other than a T3 car, then provides the power numbers- "Car is
eligible in SCCA, NASA, Trans Am GT, WRL and AER. Dyno shows 451 ft pounds of torque and 323 horsepower."
That HP number is not the power in T3 trim, with the 34mm restrictor. To support this point using Indy Runoffs data; the
Ecoboost Mustang had a 6 mph disadvantage to the 2nd place Z4. This data comes from SCCA confidential data as well as the
official race time cards.
