Would it be correct to assume that obese (wonder what happened to Tash, she had a delightful way with words) amounts of practice like this comprise mostly learning new repertoire ? It's the only thing I can think of, but not actually knowing any concert pianists I might be wrong. Surely it wouldn't be necessary for those people to do much technique practice once they reached a certain dexterity ?
I just heard Valentina Lisitsa practice's 12 - 14 hours a day. And this is what she does for fun. If you want to be the best you need to put in the time. &feature=related
Very few people can practice that much during a long time period. 14 hours every day is overpractice for sure. Sometimes you can almost hear when a pianist has been overpractising. Kissin is a pianist that sounds a like he has practised too much, Michelangeli was a bit like that sometimes too.

I agree with lostinidlewonder, especially about diminishing returns after a certain number of hours. I was advised by many fine teachers to not go over 4 hours per day (I did on average 2 a day when I played, only increasing to maximum 4 before competitions but only for a few weeks at a time - the most I clocked was 6 a day for the Schumann concerto), and to learn to practice smart instead of "long". The risk of repetitive strain injury also increases with longer hours of (not necessarily better or more productive) practice. I've seen many friends lose their wrists to physiotherapy because their teachers set them a minimum of 8 hours of repetitive, mechanical practice, and not emphasizing effective/efficient practice as well as practicing away from the keyboard.
Practice makes Perfect
To improve is to change; to Be perfect is to change often.
How many hours do you practice?I just heard Valentina Lisitsa practice's 12 - 14 hours a day. And this is what she does for fun. If you want to be the best you need to put in the time. &feature=related
