1) Different stats take longer to converge than others. For instance, if you've got 30 hands on someone and they've got a VP$IP of 85%, it's pretty safe to say they aren't the tightest players. However, after 30 hands, the WTSD% stat is pretty much meaningless.

2) It's hard for me to give a defnitive answer here. The stats are pretty much "the face" of the player for me. Players come in and out so frequently and I change tables a lot. If I didn't have these stat overlays, I'd never be able to keep reads on the player. I just look for overall trends in the stats, but they don't help me to make borderline decisions at all.

Lately, I've gotten much more involved taking notes. I section the notes by preflop/postflop. If I get 3-bet by a TAG with 66, I make a note of it. If a player peels a dry flop, and then check/raises me on the turn when he picks up a flush draw, I note it. Anything out of the ordinary goes in the notes.

The notes with the stats paints a decent picture of how the player plays. In LHE, I would never want to play w/o it.
