Park Factors Updated (1/4 Season Update)

Now that we are more than a quarter through the season, I figured that I would update the park factors since each team has 20+ games at home and away. This should affect some of this season’s WAR and Win Shares numbers since all these statistics are park adjusted. Also, keep in mind that it will very slightly affect the 2010 and 2009 numbers as well since park factors are done in 5-year spans. I plan on updating the park factors again around the All-Star Break.
