Mark,
For many courses, the most important architectural criteria is that they buy more drinks if they finish well/with a birdie, etc. than if they finish badly, unless of course, they finish so badly the other players in the foursome offer to buy the afflicted conciliatory drinks.....but really just to laugh at him.
Jeff Warne, yes a bifurcated ball (or bifurcated courses, as Tom Doak also suggests, i.e., stop designing every course to accommodate tour pros who won't show up) is a nice idea. Until then, and considering the possibility of those happening often seems to be near zero, architects have to do something, and often, providing an additional shorter tee for "real golf" is the best solution.
Also agree that cart paths and green to tee walks are best aimed at the middle tee, which usually hosts 50%+ of golfers, makes the most sense circulation wise. If you think about it, there are three adjacency scenarios - the next hole runs the same direction, the next hole runs about 90 degrees, or the next hole reverses direction in an adjacent corridor. Of course, there will be longer walks/rides transitions in housing courses and the occasional cross over tee.
But ignoring those, same direction holes are the hardest to design for. If the back tee is behind the green, you must go past all other tees. However, if back tees are pushed back equal to the center of the green, the middle tees can be reasonably close to the back of the green. 90 degree holes are easy to design the circulation routes towards the middle tees, providing the cart path is on the same side as the direction of the next hole (i.e., next hole goes right, path is on right side of previous green) If the path is right, but the next hole goes left, then the circulation path usually goes by all tees.
Ditto for holes that reverse direction in an adjacent corridor. If next hole and cart path are both right of the current green, the path can stop and turn almost anywhere, i.e. go only as far as the middle tees, letting those 17% of players walk a bit. If path is left and next hole right, the path probably goes behind the green, but may still come to the next tee somewhere short of the very back.
I have been considering such for a decade now. That said, it is probably more useful to place the paths on the slice side of most holes, which makes them more convenient for the larger number of golfers who slice, and then let the circulation work itself out as best as possible.
I co-designed a never built course with John Fought. We had a good laugh once, debating a green design. I commented that we didn't want any bunkers blocking the side of the green where the path was going to direct walkups, (the right side in this case) and suggested a back left bunker. He commented that this would block walking circulation to the back tee and he wanted that to be direct. Frankly, neither of us had considered the other guys' experience and though process. I think we both consider both transitions now, though. LOL> Frankly, the result (for me) was to reduce even further the number of back bunkers on green designs, I might use, making sure all typical routes are considered.
