You're absolutely right that the values are different there. The win expectancy chart that I use (courtesy of Dave at THT) is dynamic based on the particular run environment, so the P does in fact change a lot when it comes to Coors Field. An example: On May 10, Dan Kolb came into a game at Coors Field with the Braves leading 5-4 in the bottom of the ninth (of course, he blew the game). The P there was .261. A few weeks later, on June 4, the Braves were visiting the Pirates and were ahead 1-0 entering the bottom of the ninth. PNC is still a slight hitter's park, yet the P there was "just" .207. I don't really know how tough it was to figure out, since I didn't do it myself, but I'm grateful that someone was able to do it. Thanks for bringing that up; that was a great point that I didn't think to discuss myself. Great question. You’re absolutely right that the values are different there.

Since Coors Field is such a different run environment, is it possible that the P values there are substantially different than elsewhere? How tough would it be to figure that out?
