Re: Ask Chuck
Each round is calculated separately for the unofficial ratings you see during a tournament or right after when the scores are first posted. Normal variation and wind differences account for the same score having different ratings both rounds.
However, unless the TD tells us otherwise, all of the scores from rounds where divisions played the same course will be processed to produce official ratings where everyone will get the same rating for the same score. When the wind was quite different for the same layout, the TD should tell us and then we'll rate those rounds separately because the course actually did play tougher in the wind and the same score should get a better rating.
