This is a kind of interesting point, at least to me.
I just started APA 9-ball a few weeks ago. My 8-ball Skill Level is 5, so I automatically started 9-ball as a 5. No problem, I get it.
Thing is, I suck at 9-ball. I've played 4 weeks now and haven't scored more than 15 points. Granted, I've been playing pretty tough players, but still. Yes, they lowered me to a 4 a week ago, and that's appropriate. (In truth, it annoys me. I'm not one who wants to have a lower handicap. I'm truly frustrated that I'm not playing to the ability of my handicap. That's the real problem for me.)
So since I had to start as an SL5, due to the fact that I had an established 8-ball handicap, I can never go lower than an SL4 in 9-ball no matter how badly I play that game?
Interesting.
(I don't plan on being that bad in either league for long. It's the point of the thing that intrigues me.)
