I've never seen anyone mention this, but when I'm deciding to call or not and calculating pot odds, I do it "backwards". What I mean is that I figure out the odds of my hand improving and then look at the bet I'm faced with and then multiply that bet by the odds (for instance, I'm faced with a $70 bet and my odds are improving are 4 to 1, so the pot has to be $280 or more for me to call).

This is backwards from every way I've ever seen it described, but does it matter? Am I doing it wrong and it's going to hurt me?

Thanks!
