Yeah. I think the point here is rough consensus and running code. Of course there’s some broad agreement that wearing a mask is good — if people are anti-mask, I don’t think they’re going to work on a mask map. So there needs to be a general understanding in early 2020 that we want three quarters of the population getting access to masks and wearing them full-time as quickly as possible, in order to lower the R value of the original strain to be below one. And that is generally understood among everyone working on mask-related projects. But exactly the specifics, there’s no fine agreement between all the 100 or so teams working on those things.
