like Split says its all about sample size.
Split explains it pretty well, a 1k sample size where you have somebody on a 15/12 tells you a lot more then 30 hands, obviously
But people do change their game, somebody might open up or tighten up. All of this Split points out his post.
So a vpip/pfr is handy to asign somebodys range, but further it doesn't really tell you much. It doesnt tell you about his post flop tendencies.
Some 14/12s play their draws passivly, some raise it on the flop, just a small example!
It also doesn't tell you if he good or not. You can have a player with very solid pre flop stats but he will mess up trough all 3 streets post flop.
The rest of the stats are worse. 3-betting stats I find pretty useless, and I can very much understand how a lot of people would disagree with me here
Stats don't tell you anything about game dynamics, or dynamics between players. 3-betting stats doesn't tell you how much somebody is 3-betting against YOU
At the micro's I think vpip/pfr is handy to have, because you play against so many unknowns. It's very good that Split points out how important sample size is, and I do believe that most people who are just starting out base their decisions way to much on the small sample size HUD stats.
I think you make a very good point that a hud shows you that there are different player types, really a good point.
