Actually, your statement is correct that with a pot greater than 8.2:1, raising or calling a raise would be positive expectation purely from a pot odds standpoint. My point was just that raising cuts your pot odds in half relative to calling since you must invest 2 bets. However, if 5 people call your raise, then your ev increases by raising since you are getting 5 additional bets to your 1 extra bet. In that case it is said you are getting the proper effective odds to raise since the effective odds take into account the extra bets your raise will bring in on top of what is currently in the pot. Pot odds only take into account the size of the pot at the time you act.
