I get that, but mask usage is not 100% for many reasons. Larger droplets hitting the wearers mask from the outside are also possible for many reasons.

Mask usage is good enough. Even better if every person in the world uses them. Want 100% effectiveness? Then stay at home.

Sorry, I didn't mean that it isn't 100% effective, although that is true too.

I meant that not everyone will wear them. The improvement is still >0 in protecting oneself.
