For Athens CC, we have both the Ross field notes and most of the Johnson drawings, including Johnson's course routing.
Having pouring over them many times, it strikes me that Johnson smoothed over a lot of the funk in Ross's field sketches. The result is that many of the most interesting features in the Ross sketches disappear in Johnson's construction blueprints.
Johnson's detailed renderings of Ross's green sketches tended to round off sharp angles. Green and bunker edges became rounder, more oblate, and less interesting than the Ross sketches. Greens that Ross set at angles in his notes were reset by Johnson to be more straight on. Some of these aren't minor differences.
In short, Johnson seemed to "clean up" much of the funk in Ross's field notes. Maybe that's what Ross wanted. Maybe Johnson - a trained engineer - did it to facilitate the work of inexperienced construction crews. Dunno. But the bottom line is that Johnson's changes were to the detriment, I think, of Ross's design intent in several cases.
I don't know whether Ross oversaw Johnson's final renderings. Ross was very busy man and I would guess had little time to attend to the details in Johnson's blueprints and ink routings. Again, dunno.
But at least at Athens, Ross's field sketches draw a more interesting course than the one that emerges from Johnson's final drawings.
