That may be the case with PT4, but in a forum conversation that assumption can't be made, nor do I believe it can be made with all other functional trackers. The OP's case in point: assuming he's playing 2c/5c NLHE, if his tracker was intelligently distinguishing between BB and bb, then his BB/100 would equal 20, not 10.
These days, I do tend to assume people mean "big blinds" regardless of how they capitalize BB, simply because NLHE dominates poker discussions and televised poker, and most newer players are largely ignorant of LHE and the concept of Big Bets. But because LHE and the concept of Big Bets are not yet extinct, I believe it's still wise to follow the capitalization convention to indicate what you mean exactly. That's just my nature as a pedant and OCD. It's not quite to the same level of using "set" and "trips" interchangeably (shudder), but it's close in my book.
