Also, the coda... I think it would be more effective if you started it a bit slower, and didn't start to accel until the last page.
Well, I DID start the accel at the last page, right? Anyway, I'll try starting slower, might be a good idea. Usually, I've done an accelerando until the chordy passage in the last couple of measures where I keep the tempo pretty steady - I see it as an accelerando to that point, rather than to the end of the movement. Stephen hough does this coda pretty damn fast in his recording - I think his first movement clocks at less than 8 and a half minute while most recordings are over ten minutes...heh.
I love the fantastic drive before the recap! Great stuff.
