Had to think a little, but the developer who started me out with the charge of creating the longest course in TX as a marketing tool, and then wanted any cart ride required between holes to make sure the course touched all parts of his 1600 acres has to be tops. He later decided the longest course wasn't great marketing after all, and we were able to shorten the course to "only" 7600 yards. And, some of that was a result of a few killer back tees with 40-50 yards difference from the next tee back.
The most interesting was the Japanese owner at Wild Wing in Myrtle Beach. After two relatively pedestrian (but well within the norm of those times for MB) Willard Byrd courses, he began speaking adamantly (mostly in Japanese) at an early meeting. At some point, he blurted out his main idea - "More fru fru".
And the most common sense came from Wilderness at Fortune Bay, after seeing my first two nearby courses at Giant's Ridge. "We think you should split the difference in difficulty between the two, sort of the "porridge is just right" sort of mentality."
Actually that sort of market analysis isn't bad. Many business types study markets for gaps in difficulty and more importantly price range. Right now, too many courses discount to rock bottom, and a few remain top end. Sometimes, you find there is a gap at say, $45 and try to build a course that feels like $75 value, but can be played at the sweet spot of $45.
