I have been trying to figure that out. I guess we will not know the true percentage until after the fact.
On the BNO website I have been using the Number of Cases and Death column to calculate. South Korea looks to be 1%, they are pretty good testers.
To get the true percentage, you have to include how many who were infected that did not seek treatment with the number of reported cases.

Or, for an older population at least, you could just follow the 705 confirmed cases taken off the Princess cruise ship. So far, four have died and 691 cases remain open. By the end of March we should have an exact figure for the fatality rate for that sort of population, probably even with additional info on the impact of certain pre-existing conditions, given the large sample size.
It won’t give us the infection rate, because all 705 are confirmed cases, but it will give us the fatality rate, or at least a good estimate (instead of all the back of the envelope stuff we’ve been seeing.)
