Never really thought of it in terms of managing expectations, just creating variety. Just yesterday, I made a conscious design decision or two based on variety, flow, reducing difficulty of one late hole, etc. (on a remodel, where lots of other things were fixed.)
As to comparing to other courses, I don't have a mindset to immediately rank a new course just above or below some other courses I have played! I do have to manage my own expecations, generally finding that I mentally downgrade a course I have heard lots about while upgrading ones that have not had as much hype.
Bandon is a good example. After reading so much here, I found I liked the Kidd course way more than I anticipated, and Tom's and Ben's course just a bit less than I anticipated. All are great courses, but I guess I compare the course to my own, often wrong, self image of it from before playing based on photos, etc. Similar to me going to the movies. Not really a Star Trek fan, so when I went to Star Wars, circa 1978?, I was expecting nothing, and came away thrilled, based on my mental image.
I will say that despite great expectations of Scotland, all those courses still wowed me. With all the newer wannabes, I can only recall being more impressed than the good reviews by a few good courses.
