Thanks.
Actually, on reflection I don't have a problem with the way the analysis was done (as reported), even though it does essentially amount to second-order statistical analysis and not a controlled study of data collection. Most of the hinkiness I have noticed over the years in SOG counting came in situations where there were repeated rebounds and heavy traffic in the crease; which usually means on the power play.
(Did player X get three whacks at the puck, or only two? Was that second whack a SOG, or did someone else's stick stop it before it reached the goalie? Sometimes hard to tell through so many bodies; and some scorekeepers, as I used to notice, seemed to be tempted to fudge the counting.)
Since PDO is an even-strength stat, these effects would tend to be much smaller.
By the way, it would be interesting to see what PDO would make of a team with a coach like Bob Johnson. Johnson's strategy, as he quite openly proclaimed, was to play .500 hockey at even strength and win games on special teams. (He was the first coach in the NHL, I have read, to make
every player on the roster play either PP or PK in practice.) The strength or weakness of a Johnson-style team would tend to lie in an area that PDO doesn't even measure.
