judging is kind of fun, kind of boring!! it depends!! by the end of a competition when you have watched the same routine about 60 times it is definitely boring!! :P
I think it helps with coaching though, because you know what to look for and the specifics of what judges will take marks off on.
I don't really judge that much, usually just a few competitions a year so I always forget what I am doing! lol.... I need more practice!

overall I think it's good! just adds another dimension to gym!
