I think this all goes back to Mackenzie's design rules.
The course must be challenging to the short handicap man and playable for the hack (Not Dr. Mac's phrase!).
The guy in the middle, the 15, will be challenged but won't have forced carries he can't make, deep rough where he can't find his ball, etc. The greens will be contoured and sloped, no flat greens to accommodate 12 stimps. He can make a good score if he plays well and manages his game well.
Look at Mac's American courses for evidence. Unfortunately some of his courses have strayed from the guiding principles. (What's up with that deep rough to the left of #16 at Crystal Downs?)
