Not sure if you guys are aware, but I got Bowl Magazine yesterday after practice which is for March/April 2016 and there is a huge article about "New average integrity rules announced for 2017 USBC Open Championships". It talks about how manipulation of a bowler's average is a serious issue and how USBC is coming up with new rules. Key changes:
1) based on most recent 27 games since 2008 using Sport Average Adjustment Scale
2) past 3 seasons of USBC league play
3) all average adjusted using SAAS
Anyone caught manipulating will be disqualified and penalized big time.
It sounds good, and I am all for it, but the USBC open championships isn't really a bagger's tournament. Anyone above 180 (at least before next year's rule change), all bowl scratch. So there is no graduated handicap scale. You could bag to get into the lower (classified) division, but that is about it.
Brackets and final standings are based on scratch scores within your division ... regular or classified.
Most baggers are doing it for handicap tournaments ... although there are always exceptions, like trying to win the league for more money.
We had a guy bowl the first 6 weeks of league with his plastic ball, then switched to his normal equipment. The guy had a slew of 18 game entries in the book ... which doesn't count for a legal average. That is usually a person to consider suspicious ... one who has 18 games in several leagues with a much higher average than the one he finishes with in the league he is establishing his book average with. But I'm probably not telling anyone anything they didn't already know.
