Thanks, Tom.
The key feature of your ranking system is to differentiate courses in the upper echelon of design achievement. As you might have guessed, I'm thinking about music ratings, which are similar because they are highly subjective. Another field where subjective ranking is used to distinguish the best from the merely excellent is restaurants.
From the Wikipedia page for the Michelin Guide:
Following the usage of the Murray's and Baedeker guides, the guide began to award stars for fine dining establishments in 1926. Initially, there was only a single star awarded. Then, in 1931, the hierarchy of zero, one, two, and three stars was introduced. Finally, in 1936, the criteria for the starred rankings were published:
- : "A very good restaurant in its category" (Une très bonne table dans sa catégorie)
- : "Excellent cooking, worth a detour" (Table excellente, mérite un détour)
- : "Exceptional cuisine, worth a special journey" (Une des meilleures tables, vaut le voyage).
Beyond golf courses, pop music, and restaurants, I can't think of another common activity that is routinely ranked in this fashion. I'm sure there are a few others. Ranking baseball players, or other sports figures, is different because there tends to be statistical evidence that correlates to personal or team success. Who is the fastest man who ever lived? It's probably Usain Bolt. Who is the greatest baseball player of all time? The stats say it's Babe Ruth, but that's a bit more complicated.
One more point. My music collection now has about 11,500 songs, and I rate them on a vague system where 1 star means "good enough to be included", and 5 stars means an all-time favorite, occasionally influenced by universal high acclaim. Over the years, the percentage of 4 and 5 star songs has fallen, despite the fact the overall quality of the collection has clearly improved. The breakdown of songs, in percentage by stars, is approximately 1-5-15-39-39-0. So for me, the logarithmic relationship breaks down when distinguishing between one and two stars. If you read the Wikipedia page for the Michelin Guide, the logarithmic relationship is maintained for 1, 2 and 3 star restaurants. There is also an interesting section on the lonely, demanding life of the Michelin rater that might resonate with the course raters.
https://en.wikipedia.org/wiki/Michelin_GuideIn my case, the reason the percentage of top rated songs has decreased has something to do with the finite nature of favorites. There are approximately seven hundred 4 and 5 star songs, favorite mantras, most of which have been been in my head for decades. It's my opinion you can only accumulate so many favorite songs. I'm not sure whether that applies to golf courses, but I think it's worth considering. I would guess the older one gets, the less open they are to being "knocked out" by a new golf course experience, because there are precious past experiences which will always exceed it.
