No Bob . . .I did not say AG wouldn't allow it being practiced in his class; just merely we discussed it as an option. Same with buddy-breathing, which is not taught anymore, but still is a very specialized option of last resort.
Buddy breathing is still taught at various levels for different agencies. I learned it in OW class in 2001 (YMCA) and afaik it's still an OW skill with SEI classes.
It's also a mandatory in-water skill for NAUI Master Diver and DM training.
That's your problem, Kevin ... you're unwilling to admit that there are things about dive training about which you're completely ignorant. You make assumptions based on nothing more than your own personal biases.
Not necessarily "end of problem" Diver0001 . . .and perhaps this is just semantics, but you do shut down the post AND ABORT THE DIVE.
However what about if you abort while at your farthest modified thirds distance in an overhead? You still have to egress before surfacing don't you? And you still have contingencies to consider if something else goes wrong before even exiting the overhead, isn't that true?
If you knew the least thing about gas management and basic dive planning in overheads, you'd know the answer to that question. You plan for a catastrophic gas loss of one tank as part of your basic gas planning contingencies. Shut down the tank and get the heck out using the methods you've trained and practiced for. If a second catastrophic failure occurs, then by all means feather. That's a one in a million possibility.
And in any case, worst-case gas loss scenarios in an overhead have absolutely nothing to do with what you would do in basic open water situations ... the risk management strategies are just too different, and there are far simpler and more effective solutions available.
Applying overhead rules to open water diving may be applicable in some cases, but generally speaking you want to use the simplest, most reliable strategies to get you to the surface. Yours doesn't pass muster in that respect. The reason you had to do it in the example you keep citing is because you were a dumb-ass, solo diving without planning your contingencies properly ... and therefore had to resort to something that was less optimal because you didn't plan for the more optimal solution of having a redundant air source available.
My solution to that problem is simple ... don't do that.

Those who can . . .just do it. Those who can't become internet board moderators and say it cannot be done.
... and those who have no rational ability to defend their position turn to gratuitous insult ... even when they have to reach for something way off-topic like "moderators" ...
It's all about initiative and will to effectively problem solve, perhaps way above the OW level in which you Diver0001 do not have this "luxury". . .
Your method doesn't pass the "effectively problem solve" test ... and yes, it's way above the OW level ... that's what we've been trying to tell you ...

Oh dear... when out of arguments one must play the "REAL moderators would agree with me" card.
Nobody agrees with you, Kevin. Moderators, instructors, users you've never even heard of.... we all think you're talking out of a gaping hole in your neck.
