Tommy -
that's one of the best questions I've seen here in a long time.
Speaking for myself, I simply couldn't/wouldn't know how to go about answering it, even with the 2 or 3 courses I know best and have played most often.
Some of that is a built-in bias of some kind, e.g. I tend to believe that if a course has very good and interesting/contoured greens it will have very good shot values; and if it doesn't it won't.
But some of it must be a lack of talent/insight/experience on my part, i.e. I don't know how to recognize and remember and evaluate a golf hole/course via the various rating criteria. I can't do it very well even in absolute terms (a single course), let alone in relative terms (comparatively, one course 'against' another).
It may also be that this is simply not how my brain works, i.e. not how I experience or think about golf courses. I'm not very good at compartmentalizing (I sometimes wish I was a lot better at it) -- all the aspects and qualities of any golf course I play seem to wash/blend in together for me.
Not until later, when I'm trying to talk about it on here, am I able to think clearly about the constituent parts. I find that, upon first playing a golf hole, I either like, dislike, or am indifferent to it -- right away, and as a whole, without separating out shot values from scenery from challenge etc.
All of this is not to say that others - like you - can't do it; only that I can't.
And if I were to conclude/speculate, I'd suggest that maybe the issue many have with the GD rankings is not only the 'collective' nature of those rankings; it is also that those rankings reflect the tastes and temperaments and experiences of a particular sub-set of golfer, i.e. the one who can do what I can't.
Is that any different/better/worse than any other collective list or rankings currently available? Aren't all those lists/ranking also reflective of a particular sub-set of golfers, just like the GD one is? I don't know the answer.
Indeed: maybe even a singular/personal/subjective list and ratings, like TD's Confidential Guide, reflect his ability to see and appreciate aspects of a golf course that I never can or will.
So, what does/should Tom's ratings really "mean" to me? Or Sean Arble's? Or Golf Digest's? The only difference I see - and I think it an important one - is that the GD rankings have a patina of 'objectivity' that come both with the collective nature of the overall scores/rankings and with the numeric aspects of the criteria.
