I think you are worrying yourself about nothing. I am an equipment technicial maint guy. and frequently have to attend schools for maintenance. Most schools have a common format. intro power and then how it technically operates section by section, followed by labs to trouble shoot and repair inserted faults. When it comes to regulators the First stages are iron horse's. they work in one of a couple of ways that have been tried and proven. For my schools our trouble shooting is based on field input to determine the most common failures. Normally 99% of all failures are comprised of a small group of problems. Those areas are trained heaviest for. The same goes for diving classes. As you reg goes,, like said by many,, it is an iron horse so long as it is maintained and used as designed. The first stage either works or it doesnt. You determine that when you do a predive checkout. most freeflowing comes from the secondary when hitting the water. That is covered by predive setup. So at this point if you have a reg problem it is not a no air problem but a too much air problem which corrects it self by venting out the exhaust ports. In the very rare event you have no air you have a buddy and cesa as a backup. So as training goes all is covered. Is it possible that an airline could fall from the sky , knock you reg out of your mouth and pinning it so you cant get it or your backup. Maybe... but the reg will not be the problem. Secondary freeflows are very common and mostly to newer divers. Likewise they are quiclky adjusted and become a no problem with just a turn of a knob.
