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?
