Dead on! When I ran at the track the ET was was 13.3 for the trap app versus 12.9 but that's because tracks have a 1 foot roll out before the clock actually starts. The MPH was identical for my time slip and track app!
Honestly it happened so fast I couldn't tell you, I didn't have the go pro because I was just goofing around. I know it was 6500+ though, I don't shift to 3rd for 0-60 times.
You know Track Apps are for track use only right?? Haha..
