The new catagory 'ambiance' makes no sense to me. It's defined as 'How well does the overall feel and atmosphere of the course reflect or uphold the traditional values of the game?'. I ask a)what are those traditional values? b) is it really important to uphold them, and c) why could an inanimate object like a golf course uphold these values more than another golf course?
I think 'tradition', "What impact has the course had on the history and lore of the game?", was a perfectly reasonable category. I enjoyed Pebble Beach and St. Andrews much more than I would have if they had been built last year for that very reason. Does 'more enjoyable' mean 'greater'? It's part of the equation. Of course, this makes it harder for newer courses to compete, which is a good reason to also include separate rankings for new and old courses a la Golfweek.
Anytime you take 8 arbitrary categories, give them equal weighting and a ninth (with 1/5 of that weighting), and add them together, any resemblance to the 'best' courses is coincidental. Could you judge the best paintings by rating them on 8 factors and adding up the scores?
Also, the difference between #50 and #100 is about 2 points with a maximum of 82. How many people rated these courses? Are the differences statistically significant?
Still if they provide a starting point for discussion, the ratings are useful...
