I was recently checking out one of those "odds charts" that shows you how to convert outs to percentages to odds.

My only question is, the chart limited the outs to twenty, with 67.5 being the highest winning percentage post flop.

But my question is, can't there be way more than just twenty outs?

Let's say you've got 56s. Correct me if I'm wrong, but aren't all the following "outs":

A-4 of any suit (4cards*4suits)=16 (gives you the low straight/straight flush)
7-10 of any suit (4cards*4suits)=16 (gives you the high straight/straight flush)
also, J-K of the same suit=3 (gives you the flush)
also, the 3 other fives and three other sixes=6 (gives you pairs, trips, quads)

=41 outs?

let's say the flop is J 7 2, none of your suit. That takes away a total of three outs; now there are 38 outs.

If, theoretically via this chart (which follows an accepted formula), one out after the flop is equal to a 4.3% chance of making your hands by the river, and with each out this number increases incrementally, then 4*38=approximately 150% chace of making your hand by the river?

Am I computing outs wrong and, if I am, can someone give me a proper method?
