This site would be an ok source if they would just use ALL available data. As you rightly stated, their “recovered” number is based on the most critical cases.
Their death rate numbers are pretty skewed as well - as it doesn’t discern those who’s death was only PARTIALLY connected to COVID-19, it doesn’t have any way to allow for the intentionally LACK of care for hundreds of cases in Italy (where they aren’t even bothering to try with elderly patients).
And of course - while flu death rates are calculated based on total flu-related deaths vs the ESTIMATED total number who contract the flu, COVID death rates are being calculated based on total confirmed cases - which by the nature of testing still means mostly those who are seriously ill with the virus. We are still below the flu mortality rate, if we use total estimated infections...
Don’t worry about the recovered number. Right now it is meaningless. # of new deaths is the number at this time.
