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.

Thank you for your letter. The performance adjustments published are the result of thoughtful consideration, data collection,
and analysis from all of the touring races throughout the 2021 season. Decisions are not based solely on a single event but all
touring races throughout every region. No BOP decision is made quickly or without careful consideration. We ask that you bring
out your cars and race. Without data on the adjusted cars further corrections can't be made. Please participate. The more data
we get, the better our corrections will be. Please see some recent changes in the GCR that include some of your requests.
