I see that the official results for the tournament now include round ratings, indicating the PDGA has reviewed all the results. Sorry to report, Stimpi, that they stole your 1040 rated round
The good news is that you shot well above your player rating for all 3 rounds. Nice job.
Regarding the Pros and Adv. Men scores, I did send an inquiry to the PDGA, as I am confused by the round ratings for the Sunday round on Double Black Diamond (A.W.O.L.) with the the changes that added about 350' of overall length. A 57 in round 1 was rated 1004, while a 57 in round 3 on the longer version was rated 998; a 58 in round 1 was rated 995, while the same 58 in round 3 on the longer version was rated 989. Seems odd.
