OHHHH that explains a lot, thank you so much! I didn't realize that most of the RPM was actually from your tachometer and not from the time bonus, so I was frustrated when I grinded really hard to get my time down a few seconds for only a marginal increase in RPM. I also didn't realize that the contour of the bowl had such a big effect, which probably explained why I was losing (I kept trying to stay in the center). Finally finished the Max Blade with your tips!
