I have a program , Drag Analyzer by Performance Trends, That gives a pretty good mathmatical model of a track run. With my car that runs very high 13's at about 100, The purported difference between the last 60' average times of the time slip and actual trap speed is about 1.5 seconds. We all know that the G-Tech is about 5-6 MPH fast for this speed. Unit is right about this. They are both off to some degree.

There was a time in the distant past, not sure how long, that they had the speed measured as an average between the traps and 60' AFTER the finish line. That encouraged all drag racers to stay in the throttle way after the finish line to inflate their time slip trap speeds. It didn't change E.T. or the winner of the race, but it did raise time slip speeds. It was for that reason that they changed the average to 60' before and finish line.
