Maybe I'm not very good at expressing myself clearly. By functional I mean the impact or usefulness of the role played by the features on the golf course; bunker placement, contouring, seed lines, slopes, ridges, spines, bowls, hummocks and the like. Specifically the placement of the man made items, use of angles, elevation changes and the relationship of golf course features to each other for the playing of the game. This type of thinking is the first thing that comes to my mind when I think of Raynornessence. Does that help?
