| I'm not entirely convinced about it. Great idea but you've introduced many levels of complexity to do away with one cell. Big deal. And if one of your two cells has failed then you are now down to one cell. Are you going to trust that to run your RB? I'm afraid I'd be either on SCR or bailout at that point.
I find the KISS when the cells are happy will react quite fast to a little bit of dil. If it doesn't react then worry. Sometimes seeing Gordon's "dancing digits" is as important as a dil flush -- it's telling you the cells are doing something.
Running a KISS is a holistic approach, you need to be aware of hearing the O2 hiss, manual O2 addition, the ADV, the OPV, depth changes and the displays. If you concentrate on JUST the displays then you substantially reduce your chances. I'm sure that applies to all rebreathers but on mCCR when you stop thinking then you stop breathing. It is absolutely not a passive rebreather, you need to be on top of it rather than just watching a display.
I hook my BOV into my offboard bailout. If I can't afford a couple of breaths off my bailout for flushes then I've undersized it. You need however much gas makes you happy and if a lot of flushing makes you happy then carry the gas.
Cheers,
Stuart
