Upon leaving the staging beams, each vehicle activates an elapsed-time clock, which is stopped when that vehicle reaches the finish line. The start-to-finish clocking is the vehicle's elapsed time (e.t.), which serves to measure performance. Speed is measured in a 66-foot "speed trap" that ends at the finish line. Each lane is timed independently."

Since you can scrub MPH at the last moment; the E.T. and the weight of the car at the scales after the pass, should be the real indicator. There are many out there that are running way more than the class minimum; therefore, when they get hit with horsepower, all they do is remove weight to stay at the top.

Thank you. You got ahead of me.That was the next phase.Those two parameters would begin flags waving.But I guess Nat'l tech has other things to do.
