No, that in part why Howe is clearly ahead, but how similar the field was ?
You can see my first message here, the comments started by looking at each their gap with their fields:
How good of a goal scorer is Gordie Howe? I am asking because everybody says he's one of the best ever. Yes he has 801 goals and is 3rd all time but it took him playing 1,767 games to get there. Just a question no disrespect to him, he's in my top 10 goal scorers all time.

What do you mean by "biggest one"? Seems you are trying too hard to combine their primes to the detriment of Howe.
Over Howe's four year peak, his GPG was
0.61 (Richard's was 0.53)
The avg. of the other players with the Top Ten GPG's (min. 200 games) was
0.37
Beliveau's best four year stretch '55 to '59, his GPG was
0.59 (Howe's was 0.54)
The avg. of the other players with the Top Ten GPG's (min. 200 games) was
0.43
Howe was 65% better than the avg. Top 10
Beliveau was 37% better than the avg. Top 10
Howe dominated the field in at least two seasons, '51/52 and 52/53, in a way that was
clearly superior to Beliveau's best season in '55/56.
This is the starting point of the argument, not their raw GPGs. If you want to try to argue that a peak Howe would not be as dominant if he was the same age as Beliveau, I would be interested to hear why.
