Actually, I had some thoughts recently about over-practising and wrong practice and so on and found a lot of similarities between learning a magic trick and learning a new piece on an instrument. I tend to play the piano a lot and found (and have been confirmed in it by expert opinion) that beyond a certain point the amount of practice doesn't make any difference anymore. So, while it is very useful to practise, say, a hard passage twenty times one after another, then there comes a point, when concentrating becomes hard because it's just too repetitive, so it gets sloppy and instead of training your muscles, you "untrain" them because the muscle memory will adopt those sloppy moves and they're really hard to get rid off again later. It's pretty much the same for magic, I find.
Another similarity is the way to practise. Say you're practising the classic pass - when you first start you do it very slowly in order to get the technique right, you watch yourself in the mirror to see what it looks like etc. Once it gets more familiar you start doing it faster and then there comes the point when you do it a hundred times in five minutes and you do that ten times a day. From my experience that doesn't really help that much. Of course, you'll soon be able to do it in your sleep, but the question is, how well will you be able to do it? When I practise the piano, even with pieces which I know well, I at least once a day practise the whole piece very slowly, maybe even hands separate, just to ensure I still keep the precision and technique and it doesn't get sloppy. I'm doing the same with magic tricks and sleights, where appropriate, and it helps.
So the bottom line is that I agree that too much practise can do more harm than good and that it's more how you practise than how much you practise. Now my magical experience is still relatively limited, so perhaps some of you out there may disagree, but that's what I found anyway.
