George,
No need to read this thread. I have lived it!
But, in general, you are correct. Most gca's think so much in terms of designing for the better player, that they never really look at the routes taken by the class B, C, D, and F players. The problem is, that if you did, you would end up with ANGC (original version) where you could play putter from tee to green. You wouldn't build courses like CB that fit the site well, but are hell on average players.
Of course, there are room for all kinds of courses, with the ANGC model being about 80% of courses, and the CB mold 10% or less, and the true freeway golf, beginners courses another 10%.
