WOHEP: Backdoor flush outs estimates

[SlantNGo]

On pages 66 and 67 where Yao covers the case of runner-runner flush and provides out estimates, there is no distinction made between what are, in my opinion, drastically different situations.

In one situation, you have suited hole cards, and one of your suit on the flop gives you a backdoor draw. For example, you hold J [img]/images/graemlins/spade.gif[/img] 2 [img]/images/graemlins/spade.gif[/img] on a K [img]/images/graemlins/spade.gif[/img] 5 [img]/images/graemlins/heart.gif[/img] 9 [img]/images/graemlins/diamond.gif[/img] flop.

In the other, you have unsuited hole cards, and two of your suit on the flop gives you a backdoor draw. For example, you hold J [img]/images/graemlins/spade.gif[/img] 2 [img]/images/graemlins/heart.gif[/img] on a K [img]/images/graemlins/spade.gif[/img] 5 [img]/images/graemlins/spade.gif[/img] 9 [img]/images/graemlins/heart.gif[/img] flop.

According to Yao, we are drawing to a 2nd or 3rd highest flush, and we should assign 1.5 outs to the backdoor. Is this the case for both situations? Shouldn't we be assigning more outs (maybe close to the full 2) for the first situation, while deducting for the second situation (maybe to just 1)?
