Where’s the Science Behind CDC’s 6-Foot Social-Distance Decree?

How far does snot travel, was a thing early in the lockdown. There is science behind the dispersion for aerosols and the square law dropoff. It turns out, they're probably applying it wrong. QUT (one of three universities in Brisbane where I live) has a specialist research unit in Aerosol droplets, PM10 and related problems, and they were amongst the 200 scientists who wrote to WHO saying "you've misunderstood aerosol dispersion risk" back last year.

Things stay in suspension in the air far longer than people think. Virus' are tiny, and survive in tiny moist form in suspension far longer than people think. Who was obsessed with larger droplets, and they are more subject to gravity over their surface-area/weight effect, and therefore are subject to square law dropoff, and that is why for droplets, we have 6ft.

Maybe one-size-fits-all "guidance" is net harmful, and local knowledge and individual risk evaluation has outperformed the supposed advice, efforts and mandates of so-called experts.
