Anyone notice that the “PLUS/MINUS” in Hockey History has changed?

[Vanzig]

Does anyone know when the NHL.com and Hockey Reference, Quant Hockey etc changed some of the longtime Hockey “PLUS/MINUS” Stats?? And WHY??

GRETZKY as we know had a Lifetime Average of +518
In One Season he had a +98 Rating,

NOW 20 years later they changed it to
Lifetime Plus/Minus to +520
And +100 in the 1984-85 season.

It’s NOT just Gretzky but Clarke, Barber, Propp and others have also had their Stats changed.

Does anyone know “WHEN/WHY” and how could these stats all of a sudden be changed? If this has already been a thread then I’m sorry.

The NHL went over the boxscores as part of NHL 100, updating a lot of data, and posting lots of new stuff.

Corrections and updates with the release of a solid amount of archival data going back to 1933-34. More will be released in time.

+/- is now available for RS as well as playoffs back to the start of the 1959-60 season.

Yes, although there are still errors in the data.
