The reality is we're trying to force a quantitative score on something using completely qualitative criteria. Name me one other competitive activity that does this outside of the music realm. Every year we get frustrated when it happens and act surprised.
When 3-5 corps are as close as they are and presenting completely different artistic programs, do we really expect humans to rationally seperate them using a number system? Ask 10 experts in a blind test who has more GE, BD or bloo and you'll get 10 different opinions. However, it's not blind so the judges, who are supposed to be the experts, can only rely on what is supposed to happen because in reality they can't be differentiated.
In other words, we can't really tell which is better so we rely on our historical perspective until something is overwhelming to convince us otherwise.
Maybe ice skating has a better approach which incorporates but compulsory requirements and artistic ones.
Having said all that, nothing will really change and with regard to judging and I'll continue to watch all the great programs. And leave before scores are announced.
