Couldn’t tell you for sure but usually the cards are fairly accurate to unbiased eye test. When the aforementioned Ferraro has one of those real bad games it’s usually reflected near the bottom of the card.
Yeah, I tend to agree, I'm just someone who likes explanations for how analytics work so we can try to make sense of them without just going along blindly, you know?
It's actually one of the things that I feel has been lacking in important ways with hockey analytics versus other sports. Like with baseball, I'm no math guy, but I read Fangraphs enough over the years that eventually all the metrics used made sense. With hockey analytics, it's often felt like people presenting numbers and just being like, "Here you go," and leaving it at that.
