Michael,
Do you remember that as we played in the rain you could see faint lines showing the boundaries of the greens before Pritchard's restoration? Those were all pretty much rounded, showing how over time the greens had shrunk and lost their original shapes. I asked the superintendent while we were playing if any dirt was moved to adjust the ground levels outside of those lines and he said "no", that the sections of the greens that were added were simply reclaimed from what were fringes or other green surrounds grass heights. Also, he said that the internal contouring of the greens was pretty much exactly as Pritchard found them to be.
Charlotte Country Club had more interpretation of the type I believe you are referring to. I earlier asked Ron about Charlotte, as those greens were even more animated than Mountain Ridge's, and also had more projections or extensions than I'd ever seen on Ross greens. He acknowledged that at Charlotte he did indeed add to those greens, that he was doing more an interpretation of what would very possibly do given the design of the holes, the terrain around the greens, and the opportunities he had to work with that land.
