>Why would we use the Diamond Princess CFR instead of China's, or Italy's, or South Korea's?
because everyone on the diamond princess was tested. So we know for sure how many cases we are dealing within the sample.
~0.3 and ~0.9% are also not optimistic guesses but the current numbers for Germany and SK. Italy sits at 9%. So the situation is either that Italy is vastly underestimating cases, or Germany and South Korea have lost a magnitude of corpses somewhere. I find the latter less likely than the former.
