2 Data
For this analysis we use data from the NHL‟s Real Time Scoring System (RTSS).
That explains the funky ratings right there. You can't draw any real conclusions about the validity of the rating sytem when you're feeding it funky data. Well, other than the fact the designers of the system deliberately created a system that would rely on incredibly inconsistent data, something that certainly doesn't boost their credibility.

They did take some actions to attempt to correct for home/away biases and shot locations in certain rinks (MSG), but there is still plenty of biases, inconsistencies, and a lack of standardization for the RTSS across the league. Too much human error and subjectivity in the system currently.
