A wonderful presentation. I thank you for going through the word involved to construct it.I'll have to leave the analysis, interpretation and judgment of your presentation to others who have more knowledge of past and present DCI judging. It is clear, though, that DCI does place more emphasis on visual than performance now-a-days. Whether that is a good thing or bad thing, I think, is up to subjective opinion.
Personally, I don't have such an opinion. When I go to see a show, I'm more concerned with the entertainment value that I get. I think visual plays a greater role in that respect.
From a Corps' point of view, though, I suspect they realize what you've shown and design their shows accordingly.
