The actual testing was done with different pressure of coughs. This was just a small snip of the whole thing. And if I'm not mistaken, the amount spread was different, but the depth of the lightest weight ones still went that far. An item in motion you are correct. This was done in untrue conditions, it should be done out in the open air with people creating normal conditions, like the air moving in different directions as people walkabout or the wind blowing. This is scare tactics again! It can be done by testing patients threw a device they tested on me before that measure lung exhaust pressure than divide the number of patients to get the pressure and distance. wow, such scientific genius! But seriously, the biggest threat isn't out in the open, it's in an enclosed space with nice recirculated, conditioned air. You will also find that low-pressure multidirectional air currents produce a wider cloud of particles with a rather limited decrease in particle travel distance.
