This entire study seems to be centered around a theoretical, mathematical model, and I didn't see any attempt to actually validate that model.
Basically, the authors seem to assume that the virus behaves according to their formulas, and show that under their assumptions, face masks work, but don't actually prove that their assumptions match reality - or did I miss something?
