- The benefit is that this algorithm will not alter the actual statistics significantly so if, for example, one Sedin has 1 extra goal compared to the other they will still be rated equally.
- It also allows significantly different scores for players who do spend significant time together given significant scoring differences, due to the fact that: a lower S1 can be made up by a higher S2.
- It doesn't chase low minute players statistics as the coefficients will be small and will have a smaller squared error.
- It produces extremes periodically (negative goals for/against), you can't score negative goals for...
- The scoring rates solutions (S1, S2) aren't very comparable between teams or even fully understandable how they got there.
- Since S1 and S2 aren't very logical, this leaves me multiplying by ice time to get an approximate "individual plus minus" statistic.
