I was forced to look up "heuristic" on the online dictionary. I sort of knew what it meant. Nice.
I really like the last couple of comments. I raised this subject for a couple of reasons. We had just discussed the Doak "0" rating, and I thought the Doak "6" ranking, in particular, was worth exploring. I like evaluating courses purely on merit, and I don't want to think of them in terms of the distance are worth traveling for. The "6" ranking seems to be an important break point in the scale which separates good from great.
Mike, maybe the answer is the other Houston courses are a "5". The "6" ranking may be overused. Let's say a wealthy businessman came to you and gave you a nice budget and said. "Build me a championship quality golf course." You put your heart and soul into the job, spending lots of time on details. After that, the proof is in playing the course, and closely correlated to how fun and exciting the shots are. I'd say a "5" is solid but unexciting, a "6" yields some real excitement, and by the time you get to "7", you have built something which regularly yields exciting plays, where players moan and groan and cheer and ooh and aah, and of course, laugh a lot, every time around.
Back into my cage. Jeff, you're right though. It's much ado about not much.
