Infections in vaccinated Americans also may be as transmissible as those in unvaccinated people, the document said, and lead more often to severe illness.
It means that if you dropped the average person with Covid Classic into a completely unexposed, unvaccinated population, they'd infect 4 people, but if they had Covid Delta they'd infect 6.
No difference between two numbers is exponential. 2 → 4 → 6 → 8 → 10 is linear. 2 → 4 → 8 → 16 → 32 is exponential. 2 → 4 is nothing.
So if COVID classic is at a 4, and Delta is at 6... that's a 50% increase? So it's more, but not exponentially more?

Problem is they're estimating the R0 of Covid delta between 5 and 9, which is uhh very not good if it turns out to be closer to the upper bound
R0 isn't some stable thing, contrary to popular belief. It is influenced by how people behave and environmental factors.
True but the behaviour of your average American is not a positive in this case either.
Yeah that's why I said that, to explain why in some places it may be higher
It's exponentially more unfortunately. R0 is exponential by nature
Ah I read your other comment and now I get it.
Here's the graph from the CDC comparing diseases. Covid delta is almost a new illness in terms of transmission
