Yes, absolutely correct. I'd say the Showtime Lakers are the poster child for fast pace in the 80s.
This is why I included the number of teams. PPG has fluctuated across eras, but total points has gone up over time.[0]
Talent dilution in the expansion from 23 to 30 teams undoubtedly had an effect on pace in the late 90s/2000s.
There's probably a good formula for determining the value of a point across eras, but I'm not going to waste too many brain cells on it.
