I've always relied on notes but now I'm starting to play 12+ MTT tables at a time I thought it was time I looked into HUDs. I probably should have done this a long time ago just to evaluate my own play.

I chose PT4 because I liked the other evaluating and hand replayer options it gives you outside of the HUD. 

Could one of you lovely gentlemnen/ladies give me a link to an article, or briefly explain for me, what are 'normal' stats for for VPIP/PFR/Fold to 3b/WSD/WTSD% and any other key stats? And how you can read the stats to give you a picture of how your opponents play and how to exploit them?

I'm sure this is rather elementary for a lot of you but I'd be very grateful for any assistance.

Cheers.
