Poker Tracker 3

Ok, so I finally got it.

Now I figured out how to use it.

Now... what are some of the most important numbers to look at? I'm using it right now and its amazing.

Also, if anyone can help me with what each number means. I mean VP and PR are pretty obvious. But what does the AF mean exactly and what numbers are good or bad there? I know it has something to do with aggression but I'm not sure exactly.

Any other tips or hints on how to get the most out of this software would be greatly appreciated.

Thanks.
