Yes, and the DP sample, which the Stanford prof also adduced to support the case made by the OP, now has a CFR of 1.4%, with 15 still critical, and 123 still I’ll— so the only way for the CFR of the DP sample is up...
" If our surmise of six million cases is accurate, that’s a mortality rate of 0.01%, assuming a two week lag between infection and death."
As others have pointed out elsewhere, more than 0.01% of the entire Italian population has already died and the total is still rising. This can't plausibly be correct. And realistically, can't even be the right order of magnitude.
Of course, the DP population is older than the US and the CFR appears to increase dramatically with age. So the CFR of DP being 1.5 percent is not inconsistent with the hypothesis that the true CFR is an order of magnitude lower.
The strong argument against OP is the flu does not usually make Italy run out of space in their morgues....
