The "OVL" field in the table above represents the overall net effect of the park's factors, with the details out to the right. A value of 1.000 in OVL would correlate to a ballpark in which stats that are about average for the league are producted. Anything above 1.05, and that stadium will probably be a noticeable hitters' park. Anything below 0.95, and you're looking at a pitchers' park.
