#13 Have "unofficial" results available before awards ceremonies.
I may lose a lot of people on this one, but hear me out. It is incredibly difficult to learn you are in 2nd place at Worlds (or whatever place at whatever event) under the microscope of everyone staring at your team the very moment you find out. Any wrong gesture or expression immediately gets immediately taken as poor sportsmanship. It is much easier on the athlete to learn their scores elsewhere and compose themselves before the awards ceremonies. I hate the "well they should have been happy to be 2nd, I know I would" argument thrown about. Under the current system, the very moment your name is called out is NOT usually pleasant. (If there are only 2 teams left, it is typically a let-down to THEN hear that you are 2nd out of those 2.)
Also, I have found more mistakes in judging than you can imagine. Tabulation errors, scoring out of range, erroneous deductions, etc. Coaches should be able to review their scoresheets before the results are "final", trophies given out, jackets/rings sized, and the lights are turned out. It is usually too late to fix a mistake at that point.
This is a little less exciting for the crowd, but better for the athletes and teams, IMO. I probably won't get much agreement on this one, I know. However, name another sport where you learn your results at the award ceremony.
