Can you define 'easy' drill for me. I spoke to someone at the Arlington competition that said he was an assistant director to a world class DCI team and he seems to think Coppell drill was about a 5 on difficulty, seem to be in the middle by his standards. What makes a drill 'difficult'? I'm not a band member or anything so I have no point of reference. I'm just a band parent trying to get a better understanding.
