I would also expect less exposure in a normal office meeting than at a dance, but I think my expectation is mostly coming from people’s faces being farther apart? I think this isn’t quite the same as what you’re saying: if at a future dance I brought the meter to the middle of the hall and stood there and found that CO2 levels were similar, that doesn’t mean that if I were to strap the meter to the my face (and route my own exhalation elsewhere) I would see the same levels?
Yes, sorry, that was confusing. In thinking about how risky a contradance event is I model it as [general air quality] * [closer to people’s faces] * [effect of masking]. I was only trying to talk about the first term, since that’s the part that can be controlled by choosing whether to have the dance inside/outside, and how ventilated you can make the space.

How do I square that with:
I think “faces being further apart” is basically what I mean in the final two sentences.
