WOC face offs

I play Center most of the time and I win Face Offs most of the time. However, I find some matches where I won't win one face off... I have at least 24 ms, 90 FO skill, I know every counter, and I get good timing prompt every time, and somehow the other player wins 100% of the face offs and Toss Ups... I won't win 1 toss up. how is this possible? I thought Toss ups were supposed to be 50/50? Is there something I'm missing?
