pokertracker stats?

PFR? Total AF? What do these terms mean on the hud? VP$P is amount of times not blinded that you voluntarily put in, but these other terms, i have no idea. Help!

Usually if you mouseover the stats will explain themselves. Also look in the PokerTracker Reference thread, as well as a bazillion other places that come up under search.

On the PT3 website there is a page (i think within PT3 if you click help it takes you there) that explains all the stats.
