I just found a rating system that is pretty nice.  And I have to say, honestly, I think I’m a B-/C+.

Reaching the B- level player level is perhaps the biggest hurdle, as a good number of players peak at the C+ level. B- players are quite capable of running racks of 8-ball or 9-ball, but they lack consistency.

After the way I’ve been playing the last few days, I feel like a D player. I can’t seem to make anything beyond the 2nd ball.  I almost always get position – but what good is that if I miss the first ball.  I seriously want to just destroy things.
