I could get the rhythm down pretty well. I listen to the sound of the button clicking rather than watching for the exclamation point. Then you just have to get a feel for how much faster each new speed is. Musicians should be good at it since ti's like playing with a metronome and changing tempo.

My record is 104. I probably could work up higher but I just worked up to 100 to get the Tiger Racket card, or whatever it is you get for that.
