Wow, ok.
First of all, what gives you the right to criticize the judges, or determine 'good judging' from 'bad judging'?
Judging is not a simple process, because much of the drum corps activity is subjective. Sure, there's some things you can measure objectively, like cleanliness and execution. But GE? Analysis of the book? There's a lot of grey area. Even seemingly objective subcaptions are often influenced by subjective opinions about what surrounds it, and how it fits into context. That's avoided as much as possible, but it can never be eliminated.
I don't mean to start some full-blown argument here. Really. Looks like we're both pretty new in terms of posting. But, I can't tolerate such harsh disrespect of the people who do so much for our activity.
Of course there's some bias involved, and judges have to work really hard to ignore it. But guess what? You're not a judge. You're a Cavies fan. I'm not a judge either, and I'm going to step back and let them do their job.
As I understand, you absolutely cannot confidently come to any conclusions by comparing scores from one competition to another. It's far more accurate to look at the point margins between two corps.
So, for example, Phantom was also at both Rockford and Minneapolis. You'll see that their percussion score went down more than a point too. Fair's fair. Nobody's being targeted, this comp's percussion was just scored lower overall.
Please, in the future, think about what the judges do for the activity before you make wild, harsh accusations.
