Not so, for example the mortalities from the diamond princess are _higher_ than the ones being used to drive those projections. The fact that it takes time for people to die has held down the estimated mortality during exponential case growth.
Effectively every reputable source is observing that the early death rate projections were substantially inflated. China's reported death rate is 0.5% - and they're the ones with the most experience with the virus. Germany only recent started random testing. They previously had a fatality rate of 2%, but after random testing they found that 14% of the population already had antibodies - thus lower the death rate down to 0.37% [1]. There's a vast difference between asking "out of the people who got sick enough to go to the hospital, what portion people infected with coronavirus died?" and "what portion of people infected with coronavirus died".
You're using old data. 2% of the diamond princess infected have died so far. Another 7% of the infected are still reported as not recovered yet.
If you have a study that projects what the fatalities would have been with a shorter isolation period (e.g. only march and first two weeks of April), that would be noteworthy. Pointing to this early CDC study as a figure for what would have transpired had the economy not been shut down is not sound.
