Agreed, and I didn't mean to call you silly...just the idea!
My main instructor tends to speak about percentages once they attack is on...If you move this way, maybe you get 51% and they get 49%...if you move some other way, maybe he gets the better percentage. Once the fight is on, it's kind of a crap shoot...so you might as well take those small increases in the odds, and train to make that happen.
Better than nothing! And I also agree that confidence tends to keep some thugs away. In the wrong enviroment though, I have seen it attract trouble.
