Correction Factor

The Correction Factor is employed when a team under performs or over performs relative to
the power rating predictions.  The greater the disparity in the actual to predicted
difference increases the amount of correction.

A team receives or loses quality points based on the 'predicted goal difference'
of a game. If a team wins, it gets quality points. If a team loses, it loses
quality points. This is done so that this factor is not unfairly influenced by
the number of games a team plays. The table below explains the number of points:


      Winning team was the underdog:
         Predicted Goal Difference was > 01  cor = 0.275
         Predicted Goal Difference was > 02  cor = 0.300
         Predicted Goal Difference was > 03  cor = 0.325
         Predicted Goal Difference was > 04  cor = 0.350
         Predicted Goal Difference was > 05  cor = 0.375
         Predicted Goal Difference was > 06  cor = 0.400
         Predicted Goal Difference was > 07  cor = 0.425
         Predicted Goal Difference was > 08  cor = 0.450
         Predicted Goal Difference was > 09  cor = 0.475
         Predicted Goal Difference was > 10  cor = 0.500

      Winning team was the favorite:
         Predicted Goal Difference was < 01  cor = 0.225
         Predicted Goal Difference was < 02  cor = 0.200
         Predicted Goal Difference was < 03  cor = 0.175
         Predicted Goal Difference was < 04  cor = 0.150
         Predicted Goal Difference was < 05  cor = 0.125
         Predicted Goal Difference was < 06  cor = 0.100
         Predicted Goal Difference was < 07  cor = 0.075
         Predicted Goal Difference was < 08  cor = 0.050
         Predicted Goal Difference was < 09  cor = 0.025
         Predicted Goal Difference was < 10  cor = 0.000

      Winning Team was neither the favorite/underdog:
          cor = 0.25

      Losing Team was the underdog:
         Predicted Goal Difference was > 10  cor = -0.000
         Predicted Goal Difference was > 09  cor = -0.025
         Predicted Goal Difference was > 08  cor = -0.050
         Predicted Goal Difference was > 07  cor = -0.075
         Predicted Goal Difference was > 06  cor = -0.100
         Predicted Goal Difference was > 05  cor = -0.125
         Predicted Goal Difference was > 04  cor = -0.150
         Predicted Goal Difference was > 03  cor = -0.175
         Predicted Goal Difference was > 02  cor = -0.200
         Predicted Goal Difference was > 01  cor = -0.225

      Losing Team was the favorite:
         Predicted Goal Difference was < 01  cor = -0.275
         Predicted Goal Difference was < 02  cor = -0.300
         Predicted Goal Difference was < 03  cor = -0.325
         Predicted Goal Difference was < 04  cor = -0.350

      Losing Team was neither the favorite/underdog:
         cor = -0.25
