I'm sick of this its less than +.5% so its a fold bull [censored]. Thats not what that means at all. It means its a marginal call not a fold. I play the 30s that means .5% is what like$1.50. If i play like you I'm missing lots of 1-1.5 moves and thats just stupid.

I think the +.5% threshold is there because you want some margin of error for the hand ranges you're using and that's one simple way of creating one.

For this particular case, with AKo, it's not really an issue as there is no range you can legitimately put villain on (to be complete, if you know villain will only push with an unpaired ace this is +$EV) which does better than break even (+0$EV), and there are plenty of ranges you can use which are seriously negative.
