Exactly. I can often say with confidence that I think one course is better than another. But that's a categorical distinction, not one with infinitely subdivisible quantitative ratings attached.
Interesting subtle distinction, but can we tell what course is better, or merely which course we like better?
Of course, between Pine Valley and a nine hole muni, we can make broad distinctions. But between, say Pine Valley and Pebble Beach for the "No. 1 Course in the USA"? Or among the top 20 in MN, from an earlier post?
Fame, how we played, who we played with, weather, maintenance, recent experience, etc. all affect our rankings/ratings, etc. That said, we all agree that rankings are pretty subjective, as well, other than they average a lot of supposedly (although this group would even argue that, most likely based on % of agreeing ratings, not actual knowledge base of the other rater) knowledgeable raters.
In the end, I conclude it wasn't even worth me typing the above opinion regarding rankings......
