You wont be anywhere near this accurate at the table though. Usually its more like... hmmm well im getting 3:1 (25%) and I think im going to win about 1/3 of the time so i call. If its close enough that decimals make a difference then it doesnt really matter what you do.
so if the pot was 100 bucks and it cost me 46 bucks to call and we assume that my read on his range is correct a call would have a positive expectation?
