How much has your 60' time changed at different tracks?

Mind you I am talking about on the same type of tires, not going from a street tire to full on slicks. I seem to be stock in the cruddy 2.3 sec. range.

interesting thought...
at dragway 42 (ohio)... on sumitomo htrzII tires, i was running consistent 2.4, and some low 2.3 times, with 16.01 1/4 times.
at norwalk, on a warmer day, i was running 2.5-2.6 on yoko paradas with a 15.8-15-9 1/4.

interesting.

i'm not sure what the deal was, b/c the yoke's are "harder", so maybe the sumi's gripped off the line, but didn't help with the high end? i think that's all on me, not tires, but i think a slightly softer tire was getting me a better 60'.
weird.
