I think I read an article somewhere by either Mike Caro or Mason Mallmuth about this. He said you should keep a running tally of all those hands where you pay off on the end. So if you are playing 5-10 and call 1 bet on the end and lose, record -$10. If you make a good call and win a $60 pot you put +$60.

If I remember correctly he says if you are losing money over the long run in this tally, you are calling too much on the end and need to tighten up. If you make too much money calling on the end it means you are calling TOO LITTLE, because the fact that you have such a positive expectation on the end means you probably fold too often with marginal hands.
