@RidleyDM @DrLeanaWen The latter likely doesn't of course, but when you say lots it's important to quantify that. Even if we take those as unmasked entirely, (meaningful) masking still seems to increase a lot with a mandate in practice.
@RidleyDM@DrLeanaWen后者当然不太可能，但当你说很多的时候，量化这些是很重要的。即使我们把这些视为完全没有遮罩的，但在实践中，有意义的遮罩似乎仍然会增加很多。
