Our coach lets us each pick an event to go first on, and then lets us compete. I haven't seen that the later scores are better, but if it was true it would probably be because of the "best for last" method. That was what my old gym used to do. They would start with the worst and work their way up to the best. It seems like a decent idea but when it comes down to the gymnasts its depressing to be first all the time.
