This option improves overall statistical accuracy by adjusting for minor variances that cannot be accounted for in the board game.
Turning on this option improves the statistical accuracy of certain players who had extreme performances. For instance certain pitchers such as Greg Maddux allow very few walks. Using this option will enable Maddux to duplicate his real-life dominance in this area. A number of categories are affected by this option including home runs, walks and strikeouts. Also pitchers hitting will be affected by using this option, resulting in less walks and extra base hits by pitchers.
This option was split out from Improve statistical accuracy -- as part of the Version 10 release.
