Statistical Oddities
Alright, I've been working on a game similar to WhatIfSports, and I was developing a set of formulas to determine defensive ability. After playing with the +/ stat, I had a hunch about the difference between the points a player scores and his +/.
Example:
Conroy scored 47 points. His +/ was 13. The difference, then, is 34.
Now, I went through the gamebygame stats for Conroy on TSN, and counted up an approximate GA by looking for each game where his +/ was below his point total. Conroy's was 36.
Notice how similar his points/+/ difference is to the total I counted up.
I did this for Iginla, and the same thing happened his points/+/ difference was 57, and the "GA" I determined was 52. I'm guessing the reason there's a slight variation is because of how the +/ stat works namely, because shorthanded goals against for a player aren't tallied.
Oddly enough, this same phenomenon goes awry when it comes to defensemen:
Tarnstrom (52 points, 37)
Plus/Minus/Points Difference: 89
"GA": 99
Niedermayer (54 points, +20)
Plus/Minus/Points Difference: 34
"GA": 50
I don't think anyone really cares, but I just thought I'd point it out for all us stats buffs!
