btw, I've got data from a masking study with 350,000 participants that says 'Surgical Masks' make a definable difference in transmission...couple that with the famous MIT Report and it's understandable why cloth masks can also provide protection...but just for a shorter period of time...talking 'minutes' in a risky environment...not 'hours'.
You, and others, seem to be hung up on a need for "Perfection" and can't quite comprehend the meaning or value of "Mitigation"...it's "All or Nothing" with you...and that's harmful to you and others.
