Pythagorean Expectation
In baseball, one can "predict" the winning percentage of a team as the ratio (scored runs)^2/ (scored runs^2 + allowed runs^2), something called the Pythagorean formula.
- Data analysis in Davenport and Woolner article.
- Mathematical analysis using Weibull distributions by Steven Miller here.
- A linear formula.
- Tweaks of the exponent 2 for baseball and its inflation to (10, 14, ?) for basketball.

Daryl Morey who seems to have extended the theorem to other sports incl, Basketball. Ref:
