So at the y, most of the time, you either gave them the primary while buddy breathing or let them die, which was the point.nor was there any exchange at the Y, provided that we had the rarer octopus rigs . . .

Amazing post. Insulting your readers twice in one short paragraph. Good job.Gotcha, no buddy breathing.
So 3 donated their octopus and 7 let their buddy die.
I ran out of fingers after that.
So there in lies the problem if we are talking about disease transmission.As far as handing someone a non working reg, this is ridiculous, it needs to be checked prior to the dive and kept serviced just like any other piece of gear
Test it once in water by pressing the purge button and test once by inhale only with end of lips on outlet if needed.So there in lies the problem if we are talking about disease transmission.
If you're testing the octopus each dive by breathing off of it, you're contaminating it, so the concern here is moot.
If you're trying to not contaminated it by not testing it, well, then you're not testing it.
Now, you could argue that just pressing the purge button gives some confidence it is working, but that's still different from breathing off it to check functionality.
You could also argue that sitting in water while diving is cleaning the reg, but the tests on covid haven't shown that to be true, and all of the post rinse tests for bacteria growth also bring that notion into question.
And it's a valid difference, but if we are talking about virus living on a surface, once you're mouth on the mouthpiece, it's contaminated. There's definitely some studying that'd need to be done to see what if any difference there are there. When we are talking about the odds of a real OOA emergency combined with the odds of someone actually being ill but being asymptomatic and being contagious and the difference in viral load on the mouthpiece after doing an underwater handoff... We are probably talking the difference between 0 cases and 0 cases depending on method.That’s the difference I see.
I think you'll find the primary answer is "because they know the reg in their mouth is the proper gas for the moment".The real question is why do tech and cave divers dive this way. They are the most extreme among us, I would think they know what they are doing.
