Rihc, I think the individual hole notations in Confidential Guide are only as to TD's 31 flavors, "not the best 31 golf courses in the world, but among the first I would take a good friend to see."
Most of the courses he notates in this way have a number of un-notated holes. Just eyeballing it quickly, Pinehurst #2 and Pine Valley have only two un-notated holes, Sand Hills only three. Conversely, Rye and Dornoch have 8 un-notated holes; Prarie Dunes, 9; Forest Highlands and Casa de Campo, 10; Durban, 11.
