Wow, So, they'll train you to be an instructor even if you have never had martial art experience before? This seems a little bit fishy to me. Unless the disclaimer says "training could take 5+ years." But even then it is misleading.
It does make it tougher when you are judging an open tournament where there are people from styles you do not know. In that case I think presentation becomes a larger factor since not all of the techniques will be the same.
