"All that bitching about factors, and there were only 1 hit at the Vegas 2 Natls, 3 hits at the Vegas div., but 6 at Pomona at 2500-3800 ft." The way I fugure the difference in performance for P/S cars at both Pomona 2 & Vegas 2, the factor is off at least .04. If you take the 6.63 #1 spot for Pomona & add the factor to it, the quickest qualifier @ vegas beat that number by .04. I believe that the factor is definately wrong. I usually run about .3 tenths slower that the best pro stocker. So that means at vegas, I could potentially run 7.00 on a 7.70 index. I think I would pass on that race, which I did.
