My answer is above...accumulative stats rolled into one. Just because they don't lay down a constant/predictive answer to wins, doesn't mean it isn't effective? The result is predictive to the clubs talent, it's going to be close, very close. The best baseball gives at the moment, unless you've came up with a better formula?
P.S. That was far from rational, have you heard of sample sizes, in silly dumb retarded results you've came up with, yes it is irrational you stunned f***ing twat.
