The risk I see in using PT w/HUD and other software like that is that you might start using it as a crutch all too often. After all, like in the stock market, past statistics do not indicate future performance. Making your decisions solely on what has just transpired at your table for the last several orbits may lead you off in the wrong direction if you rely only on the stats. You sometimes have to rely more on your instincts rather than stats.

I know a few players who use a stats HUD during tourney and ring play. But what does it really buy you other than early tendencies. Can you really judge a player in a MTT by a mere few dozen hands? Knowing how good players like to change gears mid stream, early tendencies may be too misleading.

So while you might pick up on some tidbits of information, use these tools as another opinion that you can look in on, but don't use them as a crutch to base all of your decisions on.
