Not to mention it is too complicated for practical use. And the fact that James continues to revise it - with later versions now including component for things like batting avg. with RISP, solo homers, strikeouts etc.....it just shows how earlier versions are flawed and demonstrates the perhaps impracticality of ever arriving at a truly "accurate" formula at PLAYER level.
I guess I just don't see the problem with it. Sure, it continues to evolve, but as it does it only becomes more accurate.
