Let's say team B gets 10 tossups and 10 negs,
converting 15 points on every bonus for a total of
10*(10+15)-10*5=200
Team A gets 6 tossups, converting 20 points on every
bonus, for a total of 6*(10+20)=180. Team A had 60
tossup points to B's 50, and 5 points more per bonus,
but still lost by 20.
I wouldn't actually call
this an unfair result though.
