Bracket racing. Bracket racing is a form of drag racing that allows for a handicap between predicted elapsed time of the two cars over a standard distance, typically within the three standard distances (1/8 mile, 1,000 foot, or 1/4 mile) of drag racing.
Points were also awarded to owners, and these were awarded in order of qualifying time to cars which did not qualify for a race (e.g. if 43 cars qualify, and 3 DNQ, those 3 cars would get 40, 37, and 34 points). Owner points were used to determine provisional starting positions, which is the starting order when qualifying is rained out, etc.

Awards in a race are generally based on the "gun time" (which ignores any delay at the start) as per IAAF and USA Track and Field rules. However, some races use "net time" for presenting age group awards.
