Not sure whether that makes a difference. For sure it makes showing more affordable, but other than that judges in the US and Judges in Europe are pretty much the same.
My favorite this year in Germany was the judge who was judging with 2 other judges in a show (in Germany you have sometimes 3 judges starting from 2nd level). And the next week she was showing herself and was judged by one of the judges who was her colleague the week before…. (She did pretty well) I am sure it’s totally legal and ok.
And no!!! I am not implying that US judges would do that!!!
And really it is a problem to find new judges willing to deal with all the hassle…. So I don’t complain….
