if you're just trying to get fast times and not worried about the person next to you, don't worry about your reaction time since it has nothing to do with your times.
your 60' isn't bad. i can't seem to get a 2.2 and my best is 2.3.
somewhere between 60 and the 8th is where you're not as quick. might want to work on your shifts.
fwiw, i ran consistent 15.3's stock with just kn filter in stock box. my first 15.3 slip reads:
60' 2.415
1/8 9.938
1/4 15.381
MPH 88.00
