Like Kalen, I'm not sure of the relevance of how far the 16th tee should be from the clubhouse, and I don't mean that in a snarky way. Just interested to hear your thinking.
FWIW, on my home course the 16th tee is about 50 yards away from the clubhouse, but then the 16th green, 17th tee, 15th green, 14th tee, 13th green, 8th green, 9th tee and of course the 18th green are all about a hundred yards or less. It's a busy old course.
