No, I understood your advice. I am well aware of how relief is determined. My point is if relief is given say something obvious in the rough. Say a sleeping rattle snake, you get relief, and with the measured club distance- if that puts you in the fairway, no closer to hole, you are entitled to it. No rule that states you have to stay in the rough.
Back on my topic the areas in question say areas of the sod turned over have been in the fairway. The areas of no grass can be on the fringe, The areas of patch work grass, small globs of gras can also be in the fairway or fringe- Its often very penal depending where the ball ends up despite being in the fairway
