It was $1500 for each clinic. That may be steep to you, but that's the going price for Agassi, McEnroe, Courier, and Martin (though it was supposed to be Bjorn Borg instead of Martin).
During the drills, it was just drills, but when it came time to play points, as I wrote, you could select easy, or full power mode. 80% of the people selected full power, which was not surprising. A bunch of people standing on the back of the court who weren't paying attention were getting peppered w/ Andre and Jims winners while waiting for their turns.
