I always and strongly beleive that ratings for GAYP events shall not be processed together with 3-moves and 11 man ballot. This is apple and oranges. It is well known that the percentage of draws in GAYP games is much bigger and any wins are more exceptional and honorable. Calculating rating for GAYP events seriously screwed numbers.
You are right, but I still don't think we should separate them, especially due to the fact that there are barely any GAYP tournaments anymore. District 1, ACF GAYP Nationals, and the World Qualifier are the only GAYP tourneys I think I rated. Not to mention two of those tournaments are once every two years. My thing I guess is that it would be kind of pointless to have separate ratings for GAYP. Really every checker game is a draw to begin with. I think just because one version tends to produce more draws doesn't mean we should just separate it from the rest. Just my opinion though.
