Continuing the topic of pitchers defense ratings, here are some of the model assumptions based on the rating:
1e0 assumes no change in hits/obp/tb and increase DP chances by 1.1 (out of 216)
1e16 assumes .57 obp chances and .60 tb chances and .78 dp chances (out of 216)
2e11- .56 obp chances .62 tb chances .64 dp chances
2e38 1.43 obp chances 1.64 tb chances .25 dp chances
3e8 .54 obp chances .61 tb chances .34 dp chances
4e23 1.06 obp chances 1.26 tb chances .12 dp chances
Those are just excerpts from my master defensive charts, but a pitcher with a high error rating has effectively an extra single/double on their card and one fewer dp chance than a good defensive pitcher. This adds up for pitchers over the course over 1,400 to 1,500 PA's that they will be involved with.
