Era-Adjusted Playoff Points per Game for a selection of ~30 players in NHL history

Went through every playoff year for average goals scored per team per playoff game to get a baseline and calculated adjusted point totals every year for a selection of players. While I went back to 1918, for frame of reference, the highest scoring playoff year post-WW2 is 1981 with the average team scoring 3.97 goals per game, and the lowest scoring is 1952 with the average team scoring 1.97 goals per game. For every player here I factored out their own personal contributions to these totals.

This was manually done, so while the selection of players is "random" it's a lot of the top points/points per game guys or very notable players in NHL history, or active players that have been very productive. 80s players of course take a hit, while 50s players get the biggest bump, as well as dead puck era players.

As an example, this is what Gretzky looked like year-by-year. Takes a hit the majority of playoff years in the 80s/early 90s but gets a bit of a bump in his Dead Puck Era run. Despite the significant hit, he still remains as the highest points per game here:

His actual points per game average is 1.84 points per game, but adjusted points per game average is 1.64.

Table is sorted by adjusted playoff points per game.
