The New Rating ScaleThe first thing you will notice is that everyone’s ratings have dropped by about 6-8 points. The average rating for a major league player in Baseball Mogul Diamond was about 82. The first version of Baseball Mogul was originally designed with the average player rating set at 75 (corresponding to a grade of "C" in an academic environment). But it crept up over the years until more than half of all players were clumped between 81 and 86, making it difficult to differentiate between an average player and a very good player. In last year's game, the distribution of ratings for major league players looked like this:

I used this opportunity to re-establish 75 as the major league average for all player ratings and to set the standard deviation at 7. Assuming a normal distribution, ratings for players at the major league level are now distributed on a “bell curve” like this:

Fitting all player ratings to this scale means that any specific number has the same meaning regardless of whether you are playing in 1927 or 2027. For example, a pitcher's Power rating is primarily based on their projected strikeout rate. If a pitcher strikes out batters at a rate that is one standard deviation above the league average, he is assigned a Power rating of 82 (75 + 7).
