Is this calculated by what has actually been recorded while observing the tables in a specific session, or by an average of players' recorded stats?
E.g., say you're about to open up a table with 9 other players, all of whom you have 100 hands on. All of them have 100 VP$IP so far. Now say you open the table, datamine for 10 hands, during which time everybody folds every hand. Is the table Vp$IP going to be 0 (for what's been observed in that session) or still relatively high? (an average of their past stats).
