krupicka - it's an Urban Myth that's hard to stomp out but there is no statistical basis that the ratings of the pool matter to determine the SSA. People want to believe they'll get better ratings when they play in a higher rated pool but it's not true overall. We did an extensive check back around 2005 and tweaked the formula to account for a slight bias where higher rated pools got slightly better ratings. But since then it's not only 50/50 but when higher and lower rated pools play the same course in the same event at different times, the rounds are usually averaged together so any difference in either direction is wiped out.
