I think there's problems with both:
The current existing system isn't perfect. And neither is mine. Though I think mine is better.
The judges obviously aren't perfect either. Of course I want the best possible judges, and the best possible training for the judges. But it's a separate issue,
Regarding the black/white thing -- yeah, some rounds are razor thin close. If that's the case, they'll be put at the back of the line in the scoring. For example, a razor thin round 1, scored for B, will score low and be at the very right of a RBB score.
