I visited twice with my Ultimate team mates using our Ultrastars scoring 40 over then 22 over. Two of my team managed to get a 13 over on their second/third visits.
The three of us have now got golf discs and they have done 13 and 17 over.
My two visits with shiney new discs have resulted in an 18 over and 13 over (I added a dropped shot for losing a disc, damnit!).
