Poker Tracker is there to help you make decisions, not to make decisions for you. Use it to aid you in your decisions and you will make more $$.

For instance, you raise to 4xBB and someone reraiases to 15xBB. If your PT numbers tell you that he's never raised preflop over 300 hands before and now all of a sudden he's reraising you , AA or KK is what he's holding (99 times out of 100).
