So I went ahead and did the tiebreakers for you and got the winners which were:
Week 11- Colbyutahman3 coming within 12 points of the correct score
Week 12- We had a tie for accuracy with myself and Tomasina. You can do that tiebreaker however you want but we were both within 14 points of the correct score.
You can check my work on any of these but I am pretty sure I had them all right
