Of course this assumes that the "MCCR paranoia" is what makes them inherently more closely watched, so far apparently safer... not that I wish to reignite that debate
I'm not diving in hybrid and I dont think I will..... yet
But I think the mCCR mentality should be able to keep up, if you run the eCCR setpoint as low as 0.5.

My half assed reasons for thinking so include:
  • The shearwater has a nice downloadable PPO-curve. If nothing else how can you not wish to keep that constant when you see it ofr you self. So you get a very good postdive analysis of you performance.
  • You will inherit a deco-hit for not keeping the correct PPO and though you'll probably not die anymore you still have direct incentive to keep you on your toes. Ie. as a diver a poor mCCR pilot will still get "punished".
If I ever we're to dive hybrid mode, I'd leave the setpoint at 0.5'ish, knowing that if the muck hits the fan I will have a backup for my busy hands, and allso an extra safeguard when at the surface, where I cannot allways read the HUDs (running O2-mode).

Just my "2 øre"
