Sadly 3% is the right number to use for that comparison between observed fatality in the US and earlier estimates https://coronavirus.jhu.edu/data/mortality

The estimated IFR is quite different and can’t be just swapped.

You're comparing one meaningless number to another meaningless number. What's the point?

[jashmatthews]

CFR isn't a meaningless number and the estimated IFR is useful for making predictions.

In what sense is CFR meaningful? What can you do with that number? There is little consistency between countries in testing rates or the criteria of what counts as a "case".
