I mean, it might be one thing if the judges realized that paddles below six existed early on and eights later on, but the scores are already so clustered that the audience vote is all that really matters.
I would be interested too. As a college "modern" dancer, (think Martha Grahm, Isadora Duncan, "I'm a rock, I'm a tree" style, etc. as the stereotype) we knew that they had renamed our genre to be known as "contemporary" when it came to SYTYCD.
If you are thinking of "modern" as it's referenced sometimes in ballroom, I can see where you are coming from.
