If you want numbers, I don't have them, but I also know that you have no numbers to demonstrate that a cessation of collapse is plausible. Since every bona fide investigator who's looked into the matter finds the non-cessation of the collapse unremarkable, on exactly the grounds I've cited, I will need a little convincing to believe that "it should have stopped" is any kind of counter-argument that should be taken seriously.
Try the documentary "Why the Towers Fell", for example.
So you have done no calculations but you confidently assert it had to be total collapse??
I am just saying that non total collapse would be the assumed thing and even Robertson got on the backfoot when that was put to him.
