I have added Winning Margin Power Rating. The results are pretty bad, it is the worst of the models by a significant margin. I think that using only as many equations as matches causes this model to be far too overfit to have good predictive power.

I didn't include 2008-2010 because this model was unable to predict anything for the 2010 Israel Regional because insufficient matches were played.

I also added a correlation coefficient table to the "Data Summary and Methodology" book.
