I don't see how obvious discrepancies between the official Wuhan death toll and on-the-ground accounts constitute "wild" derivations.

Moreover, Radio Free Asia is quoting named residents, so this cannot plausibly be described "anonymously sourced US propaganda" or "fake news". [1]

In general, I think one should be skeptical of any statistics produced by a totalitarian dictatorship for Western consumption.
