bb/100 means plenty, like it could mean you're the best in the world but riggerstars will arrange it such that all your flip losses with be in critical late stages. Check your chip EV and it may well read the total opposite to the bb/100 version.
Here's an example. I have the highest bb/100 in the world in SnG's, yet due to my 2-3 handed graph here I'm only marginally winning instead of sunning it up in the Bahamas.
That is over 15,000 tournaments.
