Can someone give me a general guideline/direction on how to utilize Poker Tracker to better my game. I've import a lot of my hands but I'm not exactly sure what to look for, lower, higher, etc. I would appreciate any guidance whatsoever.

Edit: I would also like to know that if I request my hand history and import it and my previous import has some of the same hands as my new import, Poker Tracker is smart enough to now record the same hand twice, right?
Best part was Xianti had to move it from beginner's circle to tools of poker. I've been trouble from the start.
