Jim:
I think you are trying to make some conceptual points without having seen enough of my work to do so ... especially having not seen Old Macdonald.
For example, in bringing up the Redan, you apparently haven't seen any of the five versions of it I've built in the past. By far the best of those is at Pacific Dunes ... a hole that's maybe 600 yards away from our Redan at Old Macdonald. So, one of the guiding principles of the new Redan was that it ought to be different than its nearest neighbor. For that reason, we built the Redan at Old Macdonald to play downwind in the summer, and that prompted a number of decisions about the green and surrounding hazards that make it quite a bit different from the hole at North Berwick, or National, or anywhere else. I think I heard that it was the least favorite hole among the Macdonald clubs; and if so, I'm not surprised, because it's deliberately different than what they expected. [And that's not just my doing, either; Jim Urbina was a driving force in not sticking too close to some of the templates.]
Also, while I take your point generally in regard to "shot-testing" holes, particularly on the par-3's ... yet three of his four template par-3's are holes where you have more than one way to get to the flag ... at the Redan you can play with a high fade or a low runner, at the Eden you can take on the Strath or steer through the entrance, and at the Biarritz you can fly it to the back or try to run the ball through the swale. Indeed, it was Macdonald who first insisted that longer holes give the club member a way around the most difficult features, by "tacking" as a yachtsman does ... which has often been cited as one good definition of strategic design. So, I think you are oversimplifying his thoughts on design.
I am never going to reduce golf course architecture to a series of templates because I've had a chance to see many, many more great golf courses than existed in Macdonald's time.
