But the percentage for when you catch could be exactly the same and your EV will still be different between a preflop call/check and a preflop raise. And I don't mean your EV on any given street. Just to be clear I'm not disagreeing whatsoever that you gain more value postflop with the smaller pot than you gain postflop with the larger pot.

If I give a shot to Eric's approach:
EV for AK when hit in raised pot = Big Pot - (%draw * big pot) + investment
EV for AK when his in unrasied pot = small Pot - (%draw * small pot) + investment

A raised pot flush draw would look something like this:
20sb - (.36*20sb) + 3

An unraised pot flush draw would look something like this:
10sb - (.18*10sb) + 1

I haven't even bothered to do the math on the two situations because I didn't really try to make the actual numbers correct. But I believe this is what Eric is trying to show - in the unraised pot you win a higher % of the time because the flush draw is folding the turn whenever he misses. I'm just not sure he's taking into account that you win bigger pots in the raised hand.
