First of all, this doesn't seem correct. Even if it is, it's a terrible way of expressing it. The denominator in that equation, [plus/minus when the player is on the ice + plus/minus when the player is off it], isn't that just equal to the team's goal differential? Well discounting powerplay goals I guess. And what if it's zero (which should be the average value)? Then you simply can't calculate relative +/- any more?
And lastly it doesn't seem to account for the sign of the +/-. Say a player's team rating was +2, and he was a +10. Simple enough, his rel. rating is 5.0 (I think).
But what if your team is a -5, and you're +3. Same difference, but suddenly you're relative rating is -0.6. Makes no sense.
Just using the difference instead of quotient seems to make more sense. Someone should straighten this out for me
Relative +/- uses the worst boxcar statistic in hockey three times and no other statistic at all. What were you expecting?
