Check out this tournament:

Everyone played the same course at the same time with one difference. On hole 13 Intermediate and below played the short tee and Advanced/Open played the long tee. That is the only difference between the two divisions, yet the ratings difference is about 40-30 points depending on the score. hmmmmm, I think I know why this happened, but any idea if the ratings will change once 'official'?
