Not really though, the 6-foot rule was based on probability of transmission at various distances for airborne/droplet viruses. Perhaps it's too conservative, but all of this is probability-based. It's mostly been validated as we did studies and metastudies throughout the pandemic -- likely could have been reduced to 3 feet as we learned more but a "6-foot rule" tends to result in maybe 4 or 5 feet distances so the initial guidance seems okay: https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)31142-9/fulltext https://www.thelancet.com/journals/lancet/article/PIIS0140-6...
