But not the assumptions on which it is based. The affidant mathematician agrees with what we've all been saying: that the correctness of Monckton's final result depends heavily on the correctness of his assumptions regarding the probability of facts in dispute. The affidant makes it plain that he has not investigated those facts nor can he confirm Monckton's estimates for their probabilities. He endorses Monckton's findings only to the text that he acknowledges Monckton has also clearly labeled his results as conditional probabilities based on disputed estimates.
If I take two cookies out of the cookie jar, I can correctly derive the number of cookies remaining by subtracting two from the number previously in the jar. If I didn't know that number, or got it wrong, then my answer is still wrong regardless of my having done the arithmetic correctly. It's wrong because the correct method was applied to unreliable, unknown, or estimated results.
Saying that something has been reasoned correctly from first principles does not prove that the first principles are themselves correct. You have failed not only to do that, but you have also failed even to understand why that was necessary.
I'm obliged to quote the father of modern computation:
"On two occasions I have been asked, 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' [...] I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question." (Charles Babbage. Passages from the Life of a Philosopher, 1864)
Monckton's pseudo-statistical conclusions are irrelevant because they're based on
numbers he pulled out of thin air. That something else was computed from them according to proper equations remains irrelevant. Your affidant even says as much, right there in the affidavit. He is unwilling or unqualified to investigate the merits of the claims to which probabilities are being arbitrarily assigned. Unlike the affidant, we
have investigated the dependent claims on their merits, and you have been utterly unable to address those refutations.
