I cant believe it!!!!

You had the first 5 rounds for Maidana, of which you reassigned two to Floyd, which means you had Maidana winning two more rounds than your final score. Let me break it down in reverse

7-5 Maidana

+1

8-4 Maidana

+ 1

9-3 Maidana

Math isn't hard. You should learn it. Notice that a one round adjustment has to be applied to both? In other words, the sum of rounds has to total 12?
