Here is that Model set up I keep talking about, from page 5:
"The metapopulation model We use a metapopulation SEIR model to simulate the transmission of COVID-19 among 3,142 US counties. In this model, we consider two types of movement: daily work commuting and random movement. Information on county-to-county work commuting is publicly available from the US Census Bureau12. We further assume the number of random visitors between two counties is proportional to the average number of commuters between them. As population present in each county is different during daytime and nighttime, we model the transmission dynamics of COVID-19 separately for these two time periods (see supplementary information)..."

There are more weaknesses to talk about, but this is enough for me.
Assumptions, Simulations, unverified and limited Model parameter, adds up to nothing robust.
Now do you understand why I can't take this paper seriously?
