How often do you practice?
Ive been slipping a little lately, but on an average day, I shed atleast about 5-6 hrs. Usually no less than 2. Those aren't usually consecutive. Sometimes half and half, or 2 here, 1 there, 3 there. I have to stay steadily proficient on three instruments, so that may all be on one, or split depending on what event is coming up. An old instructor used to say, there are 24hrs in a day, how you use them are up to you.
