PK STATS MISLEADING
PK STATS MISLEADING
Conventional statistics do a disservice to our understanding of penalty killing and power plays. Somehow the NHL considers it sufficient to inform us that about 81.7% of penalties are successfully killed. Of course we are also provided with the ever-so-important home and road splits of this data (81.9% and 81.5% respectively).
The 4 on 5 data suggests a nearly constant rate of scoring (0.0022 goals per second) over the course of a short handed situation. This translates to about 7.9 goals per 60 minutes of 4 on 5 play, the usual expression of scoring rates. This is more than 300% the rate of scoring during even handed play.
