Looking at the chart, you might think we were pretty lousy at picking winners. Calibration plots compare what we predicted with what actually happened in this case, every MLB teams chance of winning each game on the day it was played and the actual outcome of each of those games. of RAPTOR for both measuring performance and predicting it going forward.
