It sounds like your position is that every course must be seen. Surely that's necessary just for the only legitimate ratings that are done, the state association slope / ratings.
And if not, extending the cycle solves the problem anyway -- as does the new-normal in course construction.
Besides, sure the regular magazines could extend the cycle, for two reasons:
1. For a general mag (GD, GM), ratings aren't that important commercially;
2. They could recut the data to manufacture all sorts of annual lists, saving the "greatest" for once every five years. (Golf Digest has done this to a bewildering degree already, GM to a lesser extent. But both have done it.) By spending more time on each course, raters would gain a greater appreciation for the various types of merit for courses (fun, difficulty, quirk, plus non-architectural stuff) and for individual holes. They could produce *more* lists off an in-depth approach. In a five-year cycle, it could go: most fun, toughest, beautiful / glorious, play-once-in-a-lifetime. That's for courses. And / or they could lard in lists based on holes: par 3s, par 4s, par 5s, and / or risk-reward, toughest, stunning, etc.
