They may have been mistaken and at one time gave his onset date as September 24. If you want to use obsolete data to make your interpretations, I guess that is up to you. But everyone can see that it is obsolete data. Just look at the last time it was reviewed by the CDC.
They clearly state in their official up-to-date data that his onset date was September 28.
I can see you will never be able to understand that, so there's no point in discussing this particular subject again.
