Adam, especially when that defense of par concept comes out of a conversation including the phrase, "I wonder what the Tour Pros would shoot here, if they ever came."
In defense of RTJ, who I think originated the phrase for his US Open work, his work was for Tour Pros, and the USGA who wanted to
embarrass identify the best player of the year.
One point I have been trying to make here, is that as gca's, we have some obligation or at least its a good idea to use some of this new data to improve designs. If a low handicapper isn't going to be able to go for a tucked pin, using his (or the USGA Slope guide_ 12% of distance, i.e., 18 yards wide and deep for Sunday Pin, I think we ought to design it at least, say 17 yards wide and deep. Going by feel and coming out with 15 yards deep/wide isn't likely to generate the aggressive play we intended otherwise.
Or, as players get more scientific about things, maybe gca's ought to as well. That seems to be the long term trend in most fields of endeavor. Sometimes, I think the gca who would build something because Tillie did it that way would probably recommend blood letting if they had gone into medicine, LOL.
