In the thread "Transcentendal Etudes" below, Andrew has mentioned about his experience listening to one of his teacher's students who was at his early twenties and could play Chopin Etude op.10/2 twenty times in a roll without feeling any stress at his hand muscles at all. Years later this pianist would be a Cliburn Prize winner!
I tried the same thing myself. And...no, nineteen is my limit. After that it really begins to get hard on my hand muscles. BTW I can only do this at MM 116-120 which is way slow than the full speed given (144 MM) at the score I have. At full speed (144 MM) I can play it only two or three times in a roll
It is also interesting that I tend to play faster as I go up the roll, perhaps in a hurry to finish it as soon as possible.
Anyway, it has been years that I had passed my twenties and have never thought of Cliburn fortunately.
It is an interesting experience that I can suggest you to try it yourself. Can be very enjoyable.
