Outs question (not sure if it belongs in probability)

[anyjack]

After the Flop, a nut inside straight draw and nothing else is 4 outs and the odds of hitting it by river is ~5.1 to 1 and on the turn to river is ~10.5 to 1. So if I call on the flop, when there is 6 small bets assuming everything equal, is this right? Or is there some adjustment that I need to make? Should I only call if I am getting around 8 small bets on average situations? I am finding out that usually if I don't hit it on the turn the odds do not justify the next call when everything goes up in price. Does anyone have a general adjustment on the probabilities/odds for making calling decisions on the flop. Also that your call is probably only one small bet.
