My point? Familiarity with the location and the experience play a huge role. With the right buddy, I don't believe that diving a double staged scooter dive in Jackson Blue to 1/3s is 'asking for trouble'. (granted the plan actually gives me about 7 cuft more than 2/3 reserve). But that confidence absolutely has to do with personal knowledge of the cave, understanding of -actual- transit times, and distance limitations.
True, I did make something of a blanket statement, and I am a new enough cave diver that no cave is that familiar to me at this point !
