I was going to mention your 60ft times until you just listed them above. A 1.71 is a great 60' so that's not the issue.

How is your 8th ET and MPH looking? Mine is strong through the 8th but fall flat somwhere between the 1/8 and finishline. I'm trapping at 90 halfway down the track but only 112 at the finish. I think we are both encountering leaning/computer pulling timing at the top of 3rd.
