Here's the problem. If all nine opponents always call down, you make money. If 7 of them folds preflop, and the two good hands stay in, you lose alot of money, in your example. If these two hands start raising (they're good hands, after all), you lose even more.

"Hot and cold equity" (meaning how much a hand makes if there was no further betting, what you're describing) doesn't mean very much in a regular low stakes poker game.
