So far I've been using Elephant to track my progress and hands but I would like to go step further (i hope :P) and start using it to help them define my opponents and how to act against them. I would like to start with some useful stats on my HUD but I don't know which are good and not too complicated for beginners and may improve my play. I play NL games at the moment using MSS.
So what would be some useful stats to put on my HUD as a beginner?
edit: I did read Stats(1) and (2) articles.
