Chart - EV of Calling on the River... (is folding as bad as we think?)

[imitation]

I guess the reason we say call because the pot is big is because very rarely can we be so sure of our "reads" online, a 4% difference is very difficult to really identify. Given the very random nature of many peoples play makes it difficult to accurately pick a number that really is our pot odds for calling on the river, and Ed and Sklansky's idea is that generally for this reason it's better to call than fold because it's more often correct (which I think we know it is). Also for metagame reasons that I think are difficult to quantify many people have built a game around not folding much on the river.
