How many rotations are correct, VPI HW19 MkIV?

After all is said and done, you've found the right belt (stock, silk , dental floss, etc...), you've positioned your SAMA at what you think is the best possible distance so the platter can do most of the work, you've made the correct adjustments on your SDS, you've cleaned and oiled the bearing, cleaned and talcom powdered your belt (if using a VPI belt), you've set everything level,etc... Is it just me or... do you pay attention to how many rotations the platter makes after you cut power until it stops? This is of coarse after all the above is optimal? My finding is almost exactly 2 rotations. I'm VERY interested in others, if you've noticed.
