I've never had a problem with being consistant, 60ft times don't vary much. Except when I used to Super Gas race with a Chevy Monza with a 12 bolt rear and I chucked a rearend on the starting line...60 ft sucked on that pass. Now they vary from track to track a little. I feel a 2 or 3 step is hard on the engine. JMO
