I'd like to see your sources for the 2% figure. That's just noise, not even a measurable result.

Frankly I don't think there is any good mask efficacy study out there. You can't intuit it from disease spread by state or county, since there are just too many other factors that could contribute. You can't do it ethically in a lab. You can't control for people "wearing them right" or using "the right kind".

And further, I remember when the American medical societies (pre-COVID) told us mask wearing countries like China and Japan actually see zero benefit. The whole thing is a farce.
