I don't know if this will help, but here's what Garlon said about park factors:

I created the ballparks file myself for OOTP and Markus implemented it into the game. It took me months of work to complete it all. The ballpark factors are indeed accurate and yes OOTP will update the factors and the changes in ballparks as you progress thru history as long as you have "Automatically Adjust League Strategy" selected in the League Setup>Options screen.

The ballpark factors from 1901-1956 were created by running the park's scoring factors thru a quadratic formula along with the league's offensive totals to generate a Batting Avg and HR Factor to reproduce the park's scoring environment. From 1957-present we have the actual park totals of all offensive categories so I was able to calculate the BA/2B/3B/HR factors for the parks directly from the data on a per AB basis. The Bill James' method of weighting the surrounding seasons was also used to provide a bigger data sample size for the park factors.

I suggest playing with Neutralized Player stats when using the park factors.
