The IMHE model, after re-estimating, _was_ too optimistic. My argument does not hinge on the IMHE model being too pessimistic; but rather simply that the IMHE model is basically useless and thus we shouldn't base policy on it.
I expect us to have well over 100,000 COVID-19 deaths - indeed probably 3x that but I admit I haven't sat down and done the age-bracket-weighted mortality napkin math. (Basically, take each age group's IFR and multiply by that age group's population in the US, after multiplying by some constant <1 which represnts the sum of herd immunity threshold plus overshoot)
So basically, I think that COVID-19 mortality is going to be way worse than the model predicts, but given the way I view the cost of lockdown, etc, I still think the approach I am proposing is superior to locking down.
Does that make sense?
