alanti: Kat, DO NOT hold your breath!
I learned last year not to hold my breath with any request made here. Just look at the member requests that you started under Beta ... how many of those requests have been addressed? (and who asked for ambient sounds and applause?)
Anyway, as far as CC's that have some form of handicapping for their members, there are 5 courses that play to or above a 60 average. All the others are coming in lower than 60 ... with Cabo and B of F the lowest, coming in under 58. (Please note, I was not able to rank Pinehurst 2).
I was only able to find 36 tourneys from the "weekly single-round 18 hole tourneys" that had data from Tour Legends.
For CC's that are using 60 as a course rating to handicap your members ... for half of the courses, you're a bit too high.
I'd love to have a bit more data. A few of the courses are hardly ever played, and others are simply just played to death. As for Merion and Best of Hardest ... I had to use the multi-round tourneys to come up with an average. Neither had a weekly with tour-legend scores.
