Thank you very much, Mr Wolf.
Somehow I never noticed those pedal markings in my score

good thing you pointed that out. I am playing this piece on Friday in front of a very big jury and it would be rather embarrassing to make such an obvious mistake!
Maybe the whole thing is a tad slow-it IS presto con fuoco. What do you think? It's difficult to maintain a high level of accuracy if the tempo is pushed much beyond this... but maybe it's worth the risk for that extra bit of excitement no?
