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.
Yup. All this work to create an "objective" number, and yet they base it off incredibly subjective (and inconsistent) source data. If the authors of the study wanted to create something to talk about so that analysts can refine their methods further, perhaps they made a valuable contribution. As a stand-alone study, however, it doesn't look particularly useful.
