Thanks for the feedback. There will always be teams that "outperform" their statistics, and Atletico are a perfect example. Based on "expected points" statistics (done by several other analysts), Atletico outperformed their expectation by 4-5 points. My rankings are meant simply as a statistical ranking system, to be used with the so called "eye-test", not to replace it.
Yes, calling it a "world" ranking was incorrect, but I did mention in my summary that it was only clubs from the traditional top 5 leagues in Europe.
I also don't understand your claim that my score does not correlate to point total. On my page, I included a linear correlation to both points and points per match, both with very high correlations (R-squared values of .87 and .89). Could you elaborate on that?
