KHL Statistical Power Rankings Explanation

10 Oct

I developed a statistics-based power ranking that will be a weekly feature at  The idea was to come up with a system similar to the BCS ranking for (American) College Football (but less complicated).  Here is the formula and then a part-by-part explanation.

Formula by Team

∑(goal differential per match x opponent points) = RAW

I guess I could write that more formally, but basically here is how it goes.  For each game, I determine the goal differential.  So, If a game is 3-2, then there is a goal differential of 1.  The winning team will get a 1 in the cell for that game.  The losing team will get a 0.

Next, the point differential is multiplied by the number of points the team has in the standings.  Say in the scenario above that each team has 15 points in the standings.  Then the one goal differential is multiplied by 15 and the winning team receives 15 points for that game.  The losing team has 15 multiplied by zero, so teams get no points for the loss.  The totals for all games played are added together for the RAW score.

This means a couple of things.  First, the losing team is not penalized for losing.  Second, the winning team does receive an incentive by beating a team by a larger point margin.  However, just running up the score and not playing defense will not help a team in these rankings, because it is not goals scored, but goal differential.

Overtime and shutout wins are considered indirectly by multiplying these totals by the point standings.  Beating an opponent by the biggest differential who has the highest point standings will give a team the most points for a game.  Beating a lesser opponent is less significant.

The RAW score is adjusted by dividing the number of games played (GP), which gives the “Points Ranking”.

I hope this makes sense and you enjoy the KHL Statistical Power Rankings.  The first edition is here.
