Shouldn't mortality rate be determined by total dead out of total recovered? Doing it the other way, total dead out of total infected, assumes everyone infected will recover.
I've read that dead / recovered overestimates since cases that end in death tend to close more quickly than cases that end with a recovery. Neither are great though and dead / cases underestimates since some of those cases might end in death as you say.
Bottom line is it's hard to get good estimates and we should let epidemiologists do their job.
