| There comes a point when planning for multiple major failures that you just give up. Lost backgas AND lost deco gas is an example. The buddy requirements become so extreme, you should just take up golf.
And buddy seperation is a major failure IMHO, although it frequently gets short shift in many educational systems (can't speak for BSAC). It certainly did in my early NAUI/PADI classes.
Otherwise... yes, halting the escalating levels of stress is step one to making rationale decisions with the resources remaining at hand. Adding additional redundancy (beyond 1 major failure or a couple of minor ones) is less important to me than making good, clearheaded, decisions with what's typically available.
