My vote is for like a hierarchy point system. Judge by spread, then break it down like: 2 corps in correct order beats 2 corps out of order beats one corps in correct position beats one corps out of position beats just spread. So say if the correct answer is X 84.7, Y 83.2, a spread of 1.5 beats a spread of 1.4 irregardless, then go through the "tie breaking" procedures
