Whereas, if you compare fatality rates reported by Germany, SK, HK, Singapore and other high testers vs China, Italy and Spain, it's pretty clear the latter are under-diagnosing mild/asymptomatic cases, which increase their fatality rate by a factor of 10 or more.

South Korea has 1% fatality rate at the end of their epidemic, they showed .5% in the middle of this. Germany has .2% rate but it has crept up to .4% and I suspect it will continue to creep to 1%, and if they get overwhelmed it could go higher. China has a less than 1% rate outside of Wuhan, since outside that area, the health care system wasn't overwhelmed [1]. The extra deaths in Wuhan could be attributed to the health care system getting overwhelmed rather than under counting - 20 or 10% of those infected require intensive care. You quote 10% of the infected on the Diamond Princess as requiring hospitalization. With an overwhelmed health care system, that might be the death rate.

Which is to say that we have more evidence but that evidence seems to point to a desperate need for containment.

10% of symptomatic cases, not all cases, and definitely not all infected.
