PokerTracker

The notes that I see on the player icons, are they generated from my database or are they generated from whats happened as Im playing live .i.e. today?

Will they be saved and there for my when I play another day, without me configuring anything ?

They're generated from hands you've imported. The hands you import while playing always get first priority so those get updated first and then if there are historical hands in your database that haven't been processed those go next (and it continues backwards).

This data is stored in the database and will be there the next time you see a player as well - it wouldn't be worth much otherwise!
