I've got the table vpip/pfr/bb/100 stat on my hud. What does the table bb/100 stat mean? Sometimes it's green, sometimes it's red. Is it the combined lifetime winrate of all seated players? Is it money recently won and lost? If poker is a zero sum game (minus rake), how is this possible?

Thanks.

Anyone?

If they do it like HM it is the average bb/100 of the players at the table since you took your seat.
