Not going to argue about kids. We all understand the limited attention span and other problems inherent with the 12-14 hour tournaments we used to have.
But for high schoolers, I have always liked the early starts, breaks between sessions for proper meals, and time to relax and reconnect with old friends rather than the hurry up and get out mentality that seems prevalent. I never thought that 9:30 or 10:00 was too late to get out of the finals. Just my opinion
