The graph I posted literally shows how the death count cannot be right. That's the whole point. A rate of transmission slow enough to have been percolating in NY since October cannot be killing 200+ per day now unless we missed 1000+ deaths in March.
I am impressed at your ability to avoid getting this.
I'm confused by your response because as I noted my first chart did not account for the lag time in deaths. So with a seed infection starting 10/15, 1.3 on the growth rate and 3 week lag on death from original infection you have the following:
Mar 31st - 10.4M aggregate infected
Mar 31st - 1659 aggregate deaths .
By Feb 1st there were 10 deaths
Mar 1st : 120 deaths
So yes, a seed infection starting in October could yield the numbers we are seeing now. And even if you change the lag period or rate of transmission you still have to account for the fact that infections won't lead to death at the same rate for all infections, meaning obviously when older people contract the virus they are more likely to die.
So, you could even push things back further assuming that younger people will catch it first because they are the ones that are primarily taking mass transit or attending large events. Then it will trickle to the older more at risk segment of the population.
There is just no way to believe that China has had this infection since October and that we had 800k people come here from China during that time to think that the seed started later than 2019.
And for the last time - My graph was not intended to describe the situation in NY. Then you would have to play with other factors because the total population is smaller and as more people contract the virus the transmisson rate decreases (over a certain threshold of people infected). In a larger area (ie the US) that theshold is much higher and you can run a simulation up until this point without having to change your assumption of infection rate over time.
