BB/100 table stats

Does anybody watch these stats when picking tables? If so what am I looking for? While datamining or when looking to dump a table that's not working, what should I be looking for? Is it good to have a table with a large BB/100? What does it mean in relation to the stack sizes? If all is equal would the stat not stay at 0 with one losing and one winning or is it based on a table having more than it's share of $$ when every one has a average 100BB stack? I've looked around but haven't found any suggestions on this stat, mostly it's just based on VP$P and PFR%. Does it even matter what the stats are if I have three or four fish, money bag and telephone Icons at the table?

I typically just stick with VPIP, PFR and Avg. Pot for picking tables and I also look at stack sizes as one of the most important things as well, I want my fish to be deep. I will leave a table when its either filled with shortstacks [or all the fish are shortstacks] or the table as a whole gets fairly rocky. At the stakes we play there is no reason to stay at a table with only 1 fish and the rest "decent" players simply because there are so many tables available and you are bound to find a better one to sit at.

yeah i dont get this stat at all.. i guess if its positive the winners are staying, and if its negative people are rat-holing or squirelling the $$ away
