The best plausible explanation I’ve seen is that Delta’s serial interval might be much shorter, which would mean R is lower than you’d think if you assumed Delta had the same serial interval as older strains. (Roughly speaking, in the time it would take Alpha to infect R individuals, Delta has time to infect R and for each of those individuals to infect another R, leading to R + R^2 infections over the same period.) That makes it easier for behavior changes and increasing population immunity to lower R below 1.
I’ll defer to Blake if he’s done the math, but it does seem worth weighting correlated risks more strongly if they could take out all of MIRI. The inundation zone doesn’t look populated, though, so you’re probably fine.
If you go with Bellingham, will you be avoiding the tsunami inundation zone?
Do you have a source for B.1.1.7 being dominant in Italy/Israel?
Assuming it’s already dominant there, that strongly suggests that it’s infectious enough to have rapidly outcompeted other strains, but that Italy/Israel were able to push down the higher R through some combination of behavioral change and vaccination.
(Note: I can’t find any sources saying B.1.1.7 is dominant in Italy or Israel, and I’d be surprised if that were already the case.)

Is this essentially just giving you leverage in PredictIt?
This process increased my “cash” on PredictIt by $117, but it looks like it will probably pay out around 15⁄14.75*850 − 850 = $15. If I lost my $117 on some other bet, would my PredictIt balance eventually end up negative?
