they are useless because of the poor fit. those numbers of yours make no sense -but surgical masks allow 80%surgical masks: Easy to obtain; comfortable; affordable; convenient; disposable (good for situations when the mask may get wet or dirty); nose wires (if available) can be adjusted.
Cons: These masks often fit loosely. Masks with ear loops may not be adjustable enough to achieve a better fit. Masks with tie cords can provide a better fit for some people. Poor fit causes gaps around the nose and along the sides of the face where respiratory droplets containing the virus can leak in and out; designed for one-time use.

further there is no direct correlation of mask wearing and even stopping the spread
Then the latest CDC - vaxxed need masks is even more dubious. no data at all given
you can see the warning lots of "mays" and weasel words
The really counterproductive part is making vaxxed wear masks surely adds to vaxx hesitancy
Apparently somebody didn't watch the video I posted.
Did you bother to read your link? Do you understand what the word "latter" means?
I can't buy a surgical mask that consist of only a shell with a coarse pore structure. Perhaps it was possible in 1992 when the study was done but that is no longer the case. The surgical masks available to the general public all contain a filter material and are at least 3 layers. (They may be better than the ones tested in 1992.) Then the part of the study you refer to only deals with submicrometer-size aerosols which for a normal breathing person would block between 50-80% of the particles. When you go look at the actual study. https://www.ajicjournal.org/article/...05)80143-9/pdf It clearly states that a surgical mask with a filter blocks 80% of the particles that are 0.75 micrometer and larger. That leaves us with a standard surgical mask in 2021 would block 80% of particles that are larger than 0.75 micron and at least 50% of any smaller particles. Aerosols are anything smaller than 50 micrometers.A surgical mask consisting of filter material performed better than did a surgical mask consisting only of a shell with a coarse pore structure. The latter passed 80% of submicrometer-sized aerosols with little flow dependency, whereas the penetration of submicrometer-sized aerosols through the mask made of filter material ranged from 25% at a flow rate of 5 L/min to 70% at 100 L/min.
Perhaps you should start by checking out the data in any studies you try to use before you attack others for not using data.
