So to clarify, are you saying you like the idea of spotting the 9-ball (if it is pocketed illegally) on the new higher spot location, or on the original lower spot location?
To me, it is critical that a Master spot covers up the spot where the 1-ball is racked for breaking, to protect the cloth and keep from wearing a hole through the cloth. Fred, you have to remember that I'm always speaking from the viewpoint of a room owner, trying to do everything I possibly can to keep the table, the cloth, the balls, etc. in as mint condition as possible. Racking the 9-ball on the traditional Master spot location which puts the 1-ball directly on top of the cloth 4 inches above the spot with nothing it to protect it is not an option for doing in my pool room.
I can live with re-spotting the 9-ball in either of those two locations, but it just seems simpler to re-spot the 9-ball on the clearly visible Master spot as opposed to a marked spot 3-7/8" below the Master spot, and I'm certainly not going to put two Master spots on the tables - that would look hideous.
