I think a course needs to posses enough first up impact to impress the player and also contain long term interest that makes you want to return.
Agreed 100%.
do you feel it was the repeat plays of the raters that allowed them to understand those ones better and rate them higher?
I don't know for sure, Grant. I'd have to imagine so. I can't think of another reason. I am all ears.
Alternatively, did repeat play of the ones that have fallen reveal a lack of substance that became apparent and affected their opinions?
On this one, I feel more confident in my answer of; Yes. For instance, BDR is really cool. Quite special. In fact, I think it is a must play to see those quarry holes. But those holes don't make a course great. They make it cool. Do "cool" holes remain cool after you've played them 50 times? I don't think so, in this context. The members I know at BDR say most of the members play the other 18 hole courses there on a day in and day out basis, rather than the Quarry course. So that tells me something.
On the flip side, I know people who were students at St. Andrews who played the course well over 100 times while they were studying there and still jump at the chance to play it. A friend of mine, and GCAer, is a member of the St. Andrews Golf Club (I think that is the name of the club), he's played it a zillion times, still talks lovingly about it, and can't wait for his next round. THAT IS GREATNESS!
