on a related note...
that ev calc isn't right. you can't compare hot'n'cold equity to current pot odds except on the river or when calling all-in. you'd have to use 'effective pot odds', ie how much you could potentially win for the whole hand compared to what it's gonna cost you to get to showdown, not just current call vs current pot, and in no-limit, figuring effective pot odds is very problematic.
The thing that sets utter spew apart from making aggressive plays is actually understanding what the hell you're doing, so being aggressive just for the sake of it is rarely a good idea 9except for standard aggression like c-betting etc obv)

There are so so many more factors that influence calling a raise preflop. You're equity vs your opponents range is one of the least relevant. What's more important is how your hand plays, how your opponent plays, knowing the advantages to flatting etc etc. These equity caculations can give you vague groundwork to work from preflop but they're best used post flop and more specifically in spots where you're close to or going to be all in in the near future or can accurately predict what is likely to happen in X or Y situation during the rest of the hand.
