60 foot would have to be identical to make a decent comparison.

The issue is putting together consistent runs while only changing one variable. Tough to do.
Really need more passes with each example.

If your 60 foot was a 2.07 on the first pass instead of 2.15, the ET on the first pass would have likely been a 15.20 or better instead of a 30.

These reasons are why Adam is going to have a tough time finding his ultimate shift point. Especially with a 4-speed car. He is going to need to 60 foot consistently, and probably just experiment with that a while until he finds something that works best. Then start driving the rest of the track, and not change a darn thing he does, including how he shifts, and just play with shift points. Not even sure he would get enough runs in a days time to iron it all out. May be several trips to the track.
