If a virus spreads and eventually infects 80% of the population with no measures in place before burning out, then the difference in rates doesn't matter.
Let's say I eat a plate of spaghetti in 2.5 minutes and my belly will be 80% full. If I eat it is 3 minutes my belly will still be 80% full. No difference.
He admitted he was wrong about the rate the virus spread. He used Chinese numbers which was around 2.5, it now looks more like 3. This however doesn't change his original 500k or 2.2m claim
Sure it does. He even says it.
His original projection predicted a very high death rate per thousand.
His revised projection lowers the rate per thousand tremendously.
The rate per thousand goes way down because he underestimated how many people are infected.
If you think 100 people are infected and 5 die you have a 5% death rate per confirmed case.
If 1000 people are actually infected and 5 die you have a .5% death rate per confirmed case.
That's how you go from 2,000,000 dying to 20,000.
It's a heckuva error but he was doing the best he could with the info available. Still a HUGE error.
