What is deep air?....and deep air is just fine.
Actually, a PADI Tec 40 cert allows for up to 15 mins of deco on single cylinder back gas, but does require a bailout. So yet another variation.
It was revised in 2023 to 15 minutes with a dedicated deco cylinder or 10 mins on backgas (redundant first/second stages required).No, it does not. PADI 40 is 10mins deco with a single deco gas up to 50%, non-accelerated deco. But in no way it certifies to use a single cylinder...

In the case of regulator or hose malfunction, shutdown the problem valve and switch to the other reg. They also teach team mentality, so that's the plan in the case of multiple failures, including Rock Bottom for reserve gas.What’s their plan for getting to the depth they can use the deco cylinder?
You made it sound like they could have a single cylinder without redundancy if they had a deco stage or did I miss understand you?In the case of regulator or hose malfunction, shutdown the problem valve and switch to the other reg.
