Using Past Performance to Make Showdown Decision

[srt19170]

Pokertracker says that when I've played a Pair to the showdown I've won 26% of the time. Suppose I now turn around and use that number to guide whether or not I call a bet on the river. I expect to win 26% of the time, so I call a bet when I'm getting 3:1 pot odds.

If that turns out to be too liberal, my Won % will start going down. That, in turn, will force me to higher pot odds. E.g., if my showdown % drops to 10%, then I'm going to want 9:1 pot odds to call a bet on the river. Similarly, if it is too conservative, my pot odds will fall.

All other things being equal, this should eventually settle out to the break-even point.

Any thoughts on this idea?
