You didn't really answer, but I confess, I already knew the answer. Its a stringer of unknown ability or accuracy, watching videotapes and categorizing them generally. BIS won't tell you how many stringers there are or if they are tested or rated against one another. Heck, the number and placement of cameras could have a major affect on the results. It could be what statisticians refer to as GIGO. But hey, you were claiming that scrappy Cappy wasn't hit hard and that raw data openly admits to not giving that information, so what good is that? Heck, if you said you like him as a player and your impression was this and that, it would work for me. Its not like you or I are going to affect the decisions of the team or his performance.
