The ratio is one of four "weirdnesses" laid out by the author, which a lab leak might parsimoniously explain, and which, so far, other hypotheses do not neatly or parsimoniously explain.

So for you to jump to "no predictive value" is a little odd.

Since you feel well-equipped to judge the validity of the various hypotheses for the origin of omicron, which hypothesis do you think explains the information and why?

Thanks.
