I read the same. The main issue is two-fold: trying to quick-shift low RPM and not shifting with authority. If you are above 6k rpm and give a solid, positive shift it's awesome. If you are low in the revs or don't give a solid kick or pull with your foot when you shift you will have issues. I did have some mis-shifts on the track but hard on the gas or the brakes and a firm shift movement with my foot delivered really, really nice shifts
