Cecil,
The average person pulls 1.6s. The good ones pull 1.5s, and the extremely talented people (Mike Slowe) pull 1.4s. Out of 100 Busa riders, maybe 5 can pull 1.4s.
330 times are where it's really at. I never believed that until this happened one day last year at the track: I ran a 9.74 then a 9.65 ....... with 1.65 60-footers on both runs. My 330 was considerably better on the 9.65 run and it paid off.
Now I concentrate more on the 330, my 60-foots are in the low 1.6s, but I shoot for 4.10-4.14 at the 330 and always run good numbers when I do.
Hope this helps.
