Here's putting your link in context.
US total cases: 85,594
US deaths: 1300
US recoveries: 1868
This gives the following stats:
Current mortality rate: 41%
Best-case CFR: 1.52%
If we take 20% as the number of undiscovered infections, that brings the numbers down to:
Current mortality: 34.2%
Best-case CFR: 1.27%
The 85,594 are
confirmed cases. We don't have enough data to make an informed estimate of the number of asymptomatic and unreported cases.
How did you arrive at a 41% mortality rate?
At present, it is tempting to estimate the case fatality rate by dividing the number of known deaths by the number of confirmed cases. The resulting number, however, does not represent the true case fatality rate and might be off by orders of magnitude [...]
A precise estimate of the case fatality rate is therefore impossible at present.
