A) Extreme cherry picking here. Why have you excluded Ronaldo's figures in Brazil? That was a higher standard than contemporary Austria I'd argue. Also, Ronaldo's overall figure is expanded by Italy, which was far more defensive at the time than anything Haaland has faced.
B) As stated above, there are contextual reasons for the differences in mins per goal. Overall it seems pretty similar for all three.
I belive its more you cherrypicking then troylock, sorry to all for feeding the troll.
I took all Ronaldos club games from start intill sep of 00 season (he turned 23 that september, same age as Haaland will be in 4 months, also around same time he got injured and next 3 seasons he only got 40 goals.

Ronaldo also had impressive 36 national team goals same age in 49 games, here I did not bother adding the minut/goal
Source
I note that 19 of his goals is in friendlies when Brazil were world champions
Ronaldo club stats up till 23:
Games: 191
Goals: 152
Minutes: 16074
M/G - 105.75
Haaland club stats up intill now, including when he played winger as 15y/o in Norway
Games: 220
Goals: 177
Minutes: 14832
M/G - 83,79
If Haaland play all 90 minuts of the rest of the season intill he is 23 (same age as Ronaldo stats) without scoring a goal his goal rate will go down to 91.3 M/G
Still better then Ronaldo same age.
You have a point if you argue age 17-20 Ronaldo scored more, but after 20 Haaland have overtaken him both in goals scored and minuts per goal. Of course from then Ronaldo had his injuries so if Haaland keep fit he we go even futher ahead from now.
They are actually really close in goals same age, if you include National team Ronaldo got 188 while Haaland is at 198, but Haaland got 4 more months to add to that number.
