I just ran a pitcher analysis through 102 games, for league 1. Using their real life Games and Games Started, I split the pitchers into three groups...
SP are define as having started at ;east 75% of their games (Group 1)
RP are define as having relieved at least 75% of their games (Group 3)
SP/RP are all pitchers that start between 25% and 75% of their games (Group 2)
Applying the same number of SIM innings pitched to their real life stats, I can easily do a comparison between their Actual ERA and Sim ERA. Same thing with whip.
It should be no surprise to anybody that the Group 3 (RPs) perform the worst in the sim. Here is a chart that summarize these results...

If I take a subset of just the best pitchers (defined as pitchers with a real life ERA < 2.50), the results look the same...
