before my last recital i asked this question as well but i don't remember getting any good answers.
they don't look/sound like good answers.
I am going to recommend practicing HANDS SEPARATELY one phrase/hand position at a time. The speed needs to be worked up to at least 160 BPM. 168 BPM would be better if you can manage it. 176 BPM would be even better still.
i actually found a video of glenn gould performing this piece at around 176 BPM.
