Drumcorps scores are completely random. Scoring is set up as an expression of ratios (like there could really be a true zero), but at best scores are intervals. I've always thought scoring should be on ordinals only, like figure skating. The attempt to assign score values gives an illusion of objectivity and fairness, but let's me honest...no one REALLY thinks drum corps scoring is objective or fair. At best, it's concensus opinion.
All to say, it doesn't really matter how high or low the score is. All that matters is where the corps places. And many corps staffs would argue even placement doesn't matter as long as the members are having a quality experience and the fans are being entertained.
Then there are the OTHER corps... DOH!
