I don't understand these numbers. But seems we have another good D-man brewing.
I struggled parsing the format as well, but I think he's saying:
He got a primary point on 32% of his teams 5v5 goals.
He got a point (primary or secondary) on 42% of his teams 5v5 goals.
He has 1.18 primary points per 60 minutes of ice time (that's _probably_ 5v5...)
He has 1.55 points (primary or secondary) per 60 minutes of ice time (that's _probably_ 5v5...)
TotCat% is his percentage contribution to even strength goal differential (I think his "contribution" to goals for as percentage of team and his "avoidance" of goals against as percentage of team?) -- I don't understand this one well enough to put it into a sentence...
He is involved in 19.5% of his teams total goals per game (individual ppg / team gpg) -- I think this includes PP.
The TotCat% and INV% attempt to adjust production and suppression for players who are on really good teams v.s. players who are on really bad teams.
