University studies are nice, but don't emulate real, golf course situations. They make the best effort, but not good enough. How many stories have you read where course X didn't aerifiy for a year or 2 to save $$ or not have to close and pay the price down the road?
As a Superintendent, I would not want to hang my hat on NOT aerifying. Way, way, way too many benefits to aerification.
