I'll play Devil's advocate and say that i'd bet the pioneers of dci and wgi surely never thought they'd see dance so heavily incorporated in the activity, both in guard and the corps, but now, through years or INNOVATION, the activity has developed and grown into what it is now. Star 97, Cadets 2000, Cavies 03, Phantom 08, I'm relatively young to the activity, but even I can see a different between my first dci show and now. While I do agree, I don't think rifles drops merit a perfect score, perhaps the judges are evaluating the whole design of the productions: staging, costumes, characterization, nuance, color, texture, choreography, technique. Perhaps it wasn't a perfect 20 based off of THAT performance, but the VISION behind it was what was evaluated. I know, I know, even sometimes I don't understand the shows until much later down the road, but the new ideas and perspectives I get from watching the Blue Devils have helped me in my design process when I teach and has really driven my program to success. Work in progress.
That all being said, these color guards are unreal good and are truly inspiring.
