Thank you....//... But I do see your point as it would be extremely hard, almost impossible to over breathe any reg.

Thank you....//... But I do see your point as it would be extremely hard, almost impossible to over breathe any reg.
I don't know you can say that, but I can breathe quite a bit of air.

The recall on Oceanic is a unique problem but are you saying that a diaphragm reg will deliver as consistently under 500 PSI as a piston reg will?
I have heard, from multiple people that have been diving quite a long time, that it may even free flow on your last 200 PSI. Which makes sense because of the mechanics.
Yes, take a example. I have AL legeng, it will definitely deliver air below 500psi. In fact, there are some diaphgram 1st stage will deliver more air at 500psi because IP increase with lower tank pressure.
That has more to do with turning of the diaphragm. But again, if you need to depend your life at 200psi. I think regulator isn't your first problem.
Right but the piston reg can deliver a lot more. Now I am not trying to say that is going to be very likely, but I doubt there are many people out there that could breathe more air than I could. Last time I was down I shot 2 x40 inch permit and spent 15 minutes fighting off 8 Goliath. It may not sound strenuous but I literally had to rip it out of their mouth multiple times, and use all my strength to push them away, they kept trying to bump me and spike me.

Piston does delivery more flow, but it needs to be where it matters. If you will never our breath a diaphragm, how would high flow of piston matter at all. Maybe it is nice to know the capability is there, but decision making should never depend on that realistically, right?
The problem with exerting yourself underwater is NOT where your reg can delivery the flow. Long before you get to the flow limit, you will retain enough CO2 that get our in trouble. The feeling you have after fighting off 8 goliath is CO2 retention. Not because you max out your reg's flow rate.
So the top comment kind of confirms the latter comment right? You have a chance of free flowing your air under 500 PSI with a diaphragm reg. Because of its mechanics, what I said earlier.
