Obviously gearing and brush compound have alot to do with it, but if you're changing brushes every few runs, there may be something else going on. Otherwise, why throw out good brushes? (I'm ONLY talking about STOCK Motors here)
I concur pops. If you correctly tweak your stock motor to minimise arcing you will get a heap of runs from brushes with just refacing. If you are arcing badly you kill them very quickly. Same with mod. This is one reason why people think stock is expensive, some stock motors arc badly from the box. Fix this and your gear lasts longer.
