The topic still intrigues me. Still not much time to think hard on it.
For one thing, some things I think of, like triple tiered greens, if i look hard enough, I find older examples.
Second, it occurs that if we want to look for American templates, I guess we ought to look at what's being built in China, since for the most part, they are modeling their courses as much after ours as our early architects modelled after Scotland. Exporting the style seems like it would be the acid test.
It also seems more like "general styles" as templates than holes, i.e., wall to wall paths and irrigation, residential housing on both sides, cart girls...….
etc.
