In two years of racing I think I changed my gearing 3 times and I usually went back to what I was using before. With modern quick shifters only taking .05 of a second to complete a shift the number of upshifts per lap isn't that important to me. I gear for the corners and the first 50ft of the drive out of them. On a 1k superbike you might want to gear so you shortshift in places with less grip, but on my 600 on pump gas that's almost never a problem.
