Getting closer. But you're not able to do this with "some random years from the past"...also, you need to factor in the other end of the age spectrum. You'd also want weighted factors on the quality of player and his role/ice time, ideally...your dates are off, but your concept isn't invalid...been down this road myself, similarly un-scientifically...but there's something here I predict.

Yeah I am not being scientific but there is just so much random observation and data pointing to the direction of the 1990s NHL being significantly stronger than in any other decade.
