Week 11 - Retrospective

Here are the accuracy results (accuracy = percentage of time a higher tier results in a higher median score than a lower tier) since week 6:

So far, we see that RB is the most predictable, followed by QB and WR, followed by TE and DST, and finally K is the least predictable.  At least predicting kickers is slightly better than random (random guessing yields 50% accuracy).

Updates from last week:
- Fixed DST scoring.  Wasn't account for points allowed previously.
