Uh-huh, I can play it faster, but I usually play it at a tempo of 180, and in the middle part where my hands can go out of control, usually reaches 220. But sometimes for excitement, I crank the speed up to 220, and when the middle part arrives, my hands simply went out of control and reaches around 260-270 on the metronome, without mistakes.
Did you play any of the other difficult preludes, such as G sharp minor, G minor or F minor?
I also played those preludes. There's quite easy to master, as I can figure out that there's a pattern or motive in each prelude.
The ones I've played are (if I can recall) #s 1, 3, 4, 5, 7, 8 12, 15, 16, 19, 22, and 24.
The hardest I've played is 24. Though I can play it at normal tempo (for every 8th notes 115 or per 8th note 230), it's very, very dangerous, as a miscalculation in turning your fingers on those scales can lead to disaster. I have no problem with the downward chromatic thirds scale, though.
