John:
The problem with Mike's "method" is human nature. When asked whether the greens were too fast, too slow, or just right, not many members ever want to admit they're too fast ... so the speed they ask for is higher than what's reasonable. [At Crystal Downs, I believe they were asking for 11.5 on the Stimp, on one of the world's most difficult sets of greens.]
I think the same dynamic is in play in green committee meetings generally ... nobody wants to be the wimp who suggests lower speeds, or reducing the maintenance budget.
Crystal Downs' greens last year were slower than any year in the last ten, after all the winter damage. From my point of view, the course was more fun to play than it has been in a long time. I just wish people could decouple "speed" from "good", but Mike Morris' research did not get into that.
