I don't see any so that would require custom statistics - see
this guide for the basics on custom statistics creation and
this guide for a deeper walkthrough. The latter was written for PokerTracker 3 but the techniques all apply to PokerTracker 4, the interface is just slightly different.
With regards to the database schema we have not
published it like we did for PokerTracker 3 however the meaning of database fields haven't changed in any significant way. Also forum member 'Bininu' made their own schema document for PokerTracker 4 available in
this thread.
