I guess it all depends on what style I will be playing. I usually always run throyugh the scales a few hundred times, but I always move very slowly atr first and gradually build up in speed. For the love of God, I wouldn't want to strain myself, and sometimes when you're nervous before a show, **** happens.

Just remember that it's important to realize that mistakes happen, and that you're not perfect. All we can do is try our best once we get up on stage, and there is such a thing as overpreparing. Just be sure that you have the confidence to truly absorb what the audience is feeling, and still at the same trime have enough strength to express yourself properly and in an honest manner.
