Tbh I have no idea. We can't know his perception of science.
We have characters like Thing, Iron Man, Colossus, etc with established strength under 150 tons competing with beings like Hulk, Gladiator, etc.
With this being the case we can't be too sure what the writer is thinking as an exact strength range. They are not thinking about exact science. That's why I believe that the handbooks are mostly the writer's opinions on a character's stats. I once posted an official marvel source that stated that the writers were consulted when making the handbooks.
