When you are watching a tournament table, if you have sample of the opponents, holdem manager/pt4 will load the players stats. You won't see the live stats of this specific table, but you are able to load the stats that you saw in the past.
This is 100% guarantee. Just go to HUD settings and look for the "live tracking".

I'm not asking something to datamining , but watch a table and be able to see everyone stats would be nice.
