Some interesting times:
Barere: 4:27
Horowitz: 4:40 (he also did it slower at other times)
Cziffra: 4:50 Studio... I assume there may be a live one faster...
Richter: 4:50 live in the 50s (I started the clock at the repeat)
But just to let you know, Barere tends to speed up the easy parts...
Horowitz will speed up the hard parts (in a slower version, but very entertaining)
Great "fireworks" in Cziffra
Richter plays it almost like a machine, but it does work well.
I heard that some legendary performance of the Schumann toccata would have been Pogorelich at the Montreal international piano competition. Someone told me he never heard it played any faster... and it was the main subject of conversation in the audience.
