Eddie great point, expecially where you faster guys come off the stop sometimes your in "no man land" where track prep could be marginal. Donnie Pedan several times would haze his tires when he came off his stop. 1 pass he only ran 181 mph the next 1 passes he hooked up he the TS opened and ran 191 on one pass and 192 on another, but consistency becomes marginal at best.
Just my redneck uneducated opinion
