I think there should be a 5th category: Forfeited rounds and it's worth 1 to 2 points.
This is different from conduct because conduct should refer to ad hommein attacks. Forfeited rounds would be seperate. If both debaters finish all their rounds, it's a tie in this category. If someone forfeits a round, this could have been due to lack of time, so they shouldn't lose a conduct point; people aren't future predictors. Instead, they lose the points in Forfeited rounds.
