A more important question is, does this matter?

are there major discrepancies by the time the season is over between the rankings of teams by PP "opportunities" and by "actual PP time"? My assumption has always been that the official and well-known PPO stat is a very reasonable proxy for PP time. let's see:

PP time:

PHI
CBJ
MTL
DET
LAK
CAR
FLA
CHI
NYR
PIT
VAN
SJS
ANA
NJD
OTT
TBL
CGY
TOR
EDM
STL
MIN
PHX
BUF
BOS
WPG
DAL
NYI
WSH
NSH
COL

PPO:

PHI
CBJ
MTL
DET
CAR
LAK
PIT
VAN
FLA
NYR
CHI
ANA
SJS
OTT
STL
TBL
NJD
TOR
EDM
CGY
MIN
BUF
PHX
WPG
BOS
NSH
WSH
DAL
NYI
COL

biggest outliers:

St. Louis. they had 15th-most PPO, but 20th-most PP time. (5)
Pittsburgh. 7th/10th (3)
Vancouver. 8th-11th (3)
Chicago. 11th/8th (3)
New Jersey. 17th/14th (3)
Calgary. 20th/17th (3)
Nashville. 26th/29th (3)

just three teams are off by two, so 20 of 30 teams are either right on, or off by just one.

the correlation between PPO and PP time is .9814.

therefore, I am still comfortable using PPO as a shorthand without worrying about actual PP time.
