I know but after 04 it went all down hill pretty fast.Shaq wasn't always out of Shape. He was one of the best athletes in his first 8 years in the league.
Its also well known that Bill Russell always had a much better team surrounding him. His team was filled with all-stars and hall of famers.
The average sized center wilt played against was 6ft 7 230 pounds. 
he played in the best era of centers. Most of the HOF centers came out of his era.
He basically has a lower career high ppg than Jerry Stackhouse.
I just don't see changes in pace and rules accounting for a 20 pt and and damn near 100% rebounding increase. Especially when you consider Wilt was in better condition. When did I suggest players would contain him? Players in his era couldn't contain him and he only managed 2 scoring titles and no rebounding titles but he's gonna go back to an era that requires better conditioning and has better interior players and double up his numbers?
Before 04 Shaq's points per game average was the 3rd highest in NBA History. That's a 11 year stretch. His career ppg average dropped because towards the end of his career he was basically a bench player.
edit: I read your post wrong. But how are you going to ignore FGA, FG% and usage rate? What kind of weak argument is this?
. Look at all the things being ignored to basically shyt on Wilt and exalt Shaq. Point blank Shaq didn't do anything in his era to demonstrate that he could have done what Wilt did in his era.
And anyone else in that era.
Not as weak as saying that Shaq would double his production in another era just because
Why weren't other players averaging anywhere near the scoring totals Wilt was then?
In his 50 PPG season, only 11 players averaged over 20 PPG
and yet no one came close to those numbers in that eraWilt was undoubtedly better but his numbers are greatly exaggerated. The same with bill Russell's rebounding numbers..
Adding the 3 pt line and the development of perimeter shooting also accounts for longer rebounds which centers often don't grab. Add in the change in tempo, and coaching philosophies which rest players when they have leads instead of running up the stats and you'll find that his rebound numbers would be a lot lower today. I read a study that said wilts numbers today would be projected to be at 14 rebounds per game in today's game. If you don't think Shaq who was 7ft plus and 300 something pounds wouldn't destroy centers effortlessly back then who were on average 6ft 7 230 pounds then you must be
Wilt was undoubtedly better but his numbers are greatly exaggerated. The same with bill Russell's rebounding numbers..
