I couldn't follow this personally. It seems to be scattered notes pasted into a Google Doc saved to PDF on Google Drive without a whole lot of journalistic narration. I see what sounds like science but I cannot for the life of me find where those intermediate number came from. But, here's the conclusion, as a summary: "In my Bayesian analysis, modeled after Michael Weissman's analysis I concluded PO(LL) / PO(ZO) = 1.7E-3 The product of my updates, I concluded P(LL) / P(ZO) = 2.125 The final, then is PO(LL) / PO(ZO) * P(LL) / P(ZO) = 3.6-3 I concluded that there is approximately a 1 in 300 chance that SARS-CoV-2 was the result of a lab leak." That is the structure of Bayes theorem, but I have no idea where the numbers came from.
