Not sure if this helps. Happened to stumble across it in the USGA Course Rating Book. Kenneth Ingram, UMD

12-1. Starting Point: Permanent Markers
Accurate permanent marker placement is imperative in the rating process. Permanent markers are to reflect an average placement of the movable tee markers over time. Incorrectly placed markers will make it difficult for the golf course staff to set up the course each day, keeping the effective course difficulty constant and in line with the ratings issued.
Permanent marker placement is more likely to have a greater impact on ratings than green speed, height of rough and other course maintenance practices. Courses and clubs should pay special attention to this issue and are encouraged to consult the authorized golf associations in the area for assistance in determining accurate placement.
When a single tee pad is designated for one set of tees, placement of the permanent marker at a point opposite the middle of the teeing area is appropriate. This maximizes the ability of the golf course to use the entire teeing area and gives the best chance of reflecting an average of movable marker placement over time.
When more than one set of tees uses a single tee pad, consider the percentage of a club's existing or anticipated play from each set of tees when determining permanent marker placement. Allocate the percentage of play to the teeing area and place each permanent marker at a point opposite the mid-point of each of the allocated areas. As an example, a forty-yard teeing area is to be shared by three sets of tees. The club determines that 25% of play will be from the forward tees, 50% from the middle tees, and 25% from the back tees. Allocation would then have the first 10 yards of the teeing area dedicated to the forward tees, the middle 20 yards to the middle tees and the final 10 yards to the back tee. The permanent marker placement would be at the mid-point of each of these three areas.
