The only real issue I have with the handicap system is the massive disparity in level between 7's. I have played some 7's even up in APA 8 Ball, but in other local leagues have had to play the same player giving them 5 games on 10 and should win. I am not a super 7 (639 Fargo) by any stretch of the imagination, but that seems to be a bit unfair to me. - I am not complaining, it just seems out of wack.
On a side note, I also see self proclaimed women WPBA pro's play in the APA at a skill level 5 or 6. If you are a "pro" shouldn't you be barred from the APA, which by definition is an amateur league?
At close to 650 Fargo, you would be a strong 7/9 and approaching super 7/9 status in most APA territories.
From what I've seen I think it goes something like:
525-550 is a weak 7/7, 50-55% win rate
550-575 is a standard 7/7 or weak 7/8, 55-60% win rate
575-600 is a standard 7/8 or weak 7/9, 60-65% win rate
600-625 is a standard 7/9, 65-70% win rate
625-650 is a strong 7/9, usually 70-75% win rate
650-675 is a super 7/9, 75%+ win rate
675-700 is a super, super 7/9, 80%+ win rate
700+ is essentially pro level when playing amateurs, 85%+ win rate, absurd break and run stats and should probably be banned from APA, lol. These are guys who have collected many scalps of actual touring pros in local and regional tournaments, but they aren't favorites to win any regional events.
I'm sure there are guys deep into the 700s in APA (Brian Parks, Abe Schaad, etc.), but I haven't encountered any. I would imagine they have 90-95% win rates and have probably had a few nights where their opponents never even left their chairs.
Of course, everything I said is area/territory/room-dependent.
