What did all you TGM experts do to get so good at the end of Master mode? I can cruise perfectly fine through the first 1000 speed levels, then it gets to 1100-1200 and I have to use auto-lock. A misdrop turns into three and I explode up the well. Usually I can recover but I'm stuck making singles. I know from the TAP grading chart that it's very important to make Tetrises after level 750. I've gotten all Section COOLs before in a game but wound up with a grade of only m5...a little short of the invisible roll requirements. Just what practice settings did everyone use to get more comfortable with the fast delays toward the end of Master?
