Jeffrey I haven't yet used this tip for when a player has already bet a street and you are plannig a shove. I use it for when I am given an oppurtunity to bet, either oop or opp. Your theory does make sense to me though. When you are dealing with exact scenarios and you know you will win when you hit, you can get very accurate with your bets using your equity.

Example:
Villain has AsKc
You have Ah3h

Preflop 4 bb raise you call, HU flop with Villain, pot is 9.5 bbs.
Flop: Kh 6h 9s
You have 9 outs to the nuts, and unless you get running 3's you need a heart.

Villain bets 8 bbs.
You can call or raise and have 35% equity.

Scenario 1:

If you call and the turn blanks, and he fires again for 20 bbs into a 25.5 bbs pot you would then need to call 20 bbs to win a 45.5 bbs pot or you need to call a ~44% pot bet with only 18% equity. In fact he only needs to bet 6 bbs to eliminate your direct odds (6/31.5 = 19%). If you now shove for your remaining stack, Villain needs to call 68 bbs to win a 133.5 bbs pot, or 68/133.5 for 50.9%. He needs to have ~51% equity to make his call profitable, thus you really have zero fold equity IF villain can put you on your draw.

Scenario 2:

If you raise the flop to 24bbs. Your raise has immdiate results IF you think villain will fold 59%(24/24+17.5). However Villain needs to call 16 bbs with a 41.5 bbs pot for ~39%, or he needs 39% equity to call your bet. We know that villain has 65% equity and should not fold. If villain calls, turn blanks, and you both have 64 bbs left and a 57.5 bbs pot any reasonable bet will commit him and kill your direct odds. Any 3bet/shove on the flop by villain will commit him and again kill your direct odds.

So then why raise? You are trying to get a free card when villain checks turn, because you need to see both the turn and river cards to maximize your draw. As you can see though that playing just a flush draw is not good against even TPTK, unless villain will fold.
