If the APA wasn't a serious amateur Pool league, they wouldn't bother with regionals and a national tournament. Competition (and winning) is the very inherited goal of Pool, or any sport for that matter. Only the losers say, 'It's just a game', so their self-esteem and ego can be maintained.
Their should not be a 'governer' on handicaps (23 rule), the players are adults, not 3rd graders. The APA uses less handicap levels than any other league I know of, and that is one of the main biggest problems with their system. And the BCA system, ratings from 1 to 75 for 5 man 8 ball team (15points per game x 5 games = 75 total), is exactly what makes the BCA league the best. For every level of the APA, it is equivalent to almost 11 levels of the BCA. (APA5 is equivalent BCA43 to BCA53). In BCA, each would be defined with a separate handicap level, in the APA, each would be a APA5. Therefore, sandbagging will automatically happen in the APA.
Basically, you could say the APA is a bad business model for handicaps, and then did add on rules to try to make it workable.
The VNEA was smart enough to recognize the problems with a 10 handicap level system, went to 11, and then went to 13 to alleviate some of the problems.
The BCA recognized the potential problems to begin with, and therefore built their handicap system to be truer to a person's skill level.
