I wonder if you have a more up-to-date approximation of risk ratios. I used to approximate risk ratio between a full-but-not-packed bus and 5~10% occupancy rate bus to be similar to the ratio between everyone else being unmasked vs masked with standard expectations around how well they wear them.
(I'm asking because I don't remember anymore how I was estimating that, it was quite some time ago so potentially based on outdated information, and if I'm reading you correctly you might think the first ratio is significantly smaller than the second.)
