I looked over the pitcher rankings and these changes dont really affect the rankings of the pitchers very much, if at all.

What it does chhange slightly is the points spreads between the pitchers, so, for example, Chris Carpenter, who was the #1 rated starter last year, now has a greater difference in points between himself and Johann Santana, last year's #2 rated starter, because Carpenter was 16 games over .500, giving him an additional 16 points, while Santana was only 6 over .500, so he gets an additional 6 points.
