Maybe you can now correct the "killing between 1% to 3.5% of the people it infects" part. It's horribly misleading.
IFR < CFR and IFR estimates go always down over time and never up due to the skewed nature of the data. Antibody tests are coming in already and based on them you get very accurate numbers.
Really it is not important from the perspective of doing something about this pandemic as a huge number of people will die at all estimated levels.
