The accuracy is listed for each league or region for high school boys' lacrosse. The average goal error is a measure in goals of how well the power ratings predicted the actual goal margin. 3.01 goals means that for all games played in a region, the power ratings predicted on average within 3.01 goals. The number of times the power ratings predicted within one, two, three, etc. goals is shown under the columns [0,1], [1,2], etc. So, for CT-I, the predicted goal difference was within three goals of the actual difference on 368 (133 + 128 + 107) occasions or 60.7% of the time.
