"Pardon my ignorance, but is this a hint that Coore and Crenshaw are going different ways?"
Not at all Jeff.
This thread is merely a series of mathematical formulae and applications to test the true extent of their remarkable golf architectural SYMBIOSIS.
They don't advertise this fact but I have actually seen it. They are capable of communicating with one another by simply thinking interesting and deep architectural thoughts. If they are in different parts of the world they do not need telephones of computers to do it and if they happen to be together in the same place they do not even need to speak to one another although sometimes they do---generally quite quietly, I might add.
Coore and Crenshaw are the absolute latest and last word in extrasensory perception when it comes to golf course architectural symbiosis.
I saw this once at Friar's Head. It was quite windy and they were speaking very softly. So I was hovering right behind them trying to listen.
Soft words and then long periods of quiet.
At one point, Bill said to Ben:
"That's not what you just thought."
Ben said:
"But I didn't say anything".
Bill said:
"Maybe not but that's what you just thought."
And Ben said:
"I guess you're right, I did think that even if I didn't say it."
Damnedest thing I ever witnessed and right in front of my eyes the entire concept of Friar's great little 5th hole was born through extrasensory perception.
