Back of envelope estimate ( but from a good guy) of 11% new Delta spread.

Interesting: “sequence data suggests Rt of Delta variant of 1.18 “
I assume the low Rt (not R0) is from “wall” of vaxxed and prev infected.
Some more good news. Shockingly, it seems one of the favorite Quacksters favorite predictions of needing a “software upgrade” every few months to a year depending on their level of delusion is wrong.

Seems like he is estimating a wave from Delta about half as big as last Winter's wave (30-something Million vs. 65 Million).
It might vary in other ways as well. My speculation: possibly lower fatality rate, possibly a faster peak.
Arkansas is mow one of the leading States for the Delta variant, as a percentage of new Cases, along with Missouri, Utah and Colorado. Like Los Angeles, it is already the dominant strain there. From your link:
