I agree, you can't read much into that by itself.
But for the hell of it, my best in pure $ is QQ9 -- and my second-best is QQ8.
As far as BB/Hand, my best is JJJ and my second-best is 333. The best non-trips starting hand is AQQ (behind also AAA and TTT). Then I have 888, 444, KKK, 666 before I get to QQ9.
My worst BB/Hand is 999. I've had it three times, dropped two big pots with it (to a flush and a full house). The only win was a small one. My second-worst is 998.
My worst in $ is KJT, with JJ9 not far behind.
Another thing I notice is that I've started with AAx 207 times with a win % of 63% and have only won .59 BB/hand with it. Scrolling through the history, I see a lot of small pots won and a few big pots lost with it.
