IIRC, the Jones Trail really was in the fast food mode, as many, if not all of them started at the same time and RTJ had to implement some system to get the designs submitted on time for the contractors. My memory could be faulty, and for that matter, they might have only had to rush the first few designs to get started and supply the others later and with much less pressure. Who knows, maybe the site work and driving ranges were done first to give them more time to design.
I would guess most architects tend to re-use 30-45 green concepts, and maybe 15-25 fw concepts, adapting them each time. I doubt many "force" designs on a site where they don't fit. Rather, they look at the site and figure which green is the best starting point for design. A typical example being finding a reverse slope site, and immediately pulling a Redan out of the file as a starting point. it's that, a Ross reverse (12 at WBYC or 14 at Oakland Hills) or perhaps reducing the back to front slope from the normal 2%, or flattening to 0% and draining cross ways to fit the ground. Even so, filling in the details always makes them slightly different in path location, bunker depth, drainage and what not.
