That is why I say the APA is brilliant. Everyone that plays for any length of time will get better. So eventually the team will be too strong and the higher SL players will be forced to quit the team and start there own if they want to play in the APA. This is why I say it is a pyramid scheme. The higher SL you get the more likely you are to have to start a new team and find some weak players.
That isn't necessarily true, at least around here. (And yes, every area is different, even though we all feed into the same computer system. Interesting.)
I've been playing APA for about 5 years. What I've seen is that many folks will improve once they start playing regularly, but they will only improve so far...and then settle in to that skill level. Note that I said "many" folks. There will always be some who truly drive themselves to improve and have the ability and time to do so. Still, the majority of casual league players will settle in to their skill level and remain there, within one level up or down, for the most part.
We have had a few folks go right up through the skill levels, up to 7/8. But we have a large, very large majority who stall out at SL5. A few bump up to SL6, and some of them come back down to SL5 again. Same with the SL3's and SL4's. Most folks here seem to hit their ability level, and hang there.
Is this an indictment of APA, and that ALL these folks are sandbagging, no. These folks are trying to win, and playing their once or twice a week pool matches, with no real concentrated effort to improve in a dramatic way. Doesn't mean they don't care, or that they aren't trying to win, just that they don't play pool a lot and they aren't driven to improve in their spare time.
That having been said, we occasionally have one or two teams that get out of balance because a few of the newer players move up, and haven't found their playing level yet. But we rarely have teams break up because of Skill Level issues. And we have between 8 and 14 teams most sessions.
A large majority of us have been playing for at least a few years, many for a very long time. We can always manage to get a player onto another team. Or that player might decide they want to make a new team, and a few of the teams shuffle players, yes bringing in some new blood as well. Then again, we all like playing, and we all get along, so perhaps this is why it isn't such a big deal.
It is a shame that the APA brings more new people into the game, isn't it?
It sounds like the OP is one of those "better" players who probably should be playing in a different format. Still, I will maintain that you can play an SL7/8 if you want to, and you don't have to go changing your team all the time. It can happen, it has for me and for ours for the last 5 years that I've played. (I will admit handling an SL9 must be quite a challenge. Never had that experience.)
