Hi all and thank for an interesting thread.

I'm with Michael on this one, consisten pattern is key to good reaction time.

Would using an orifice for basic flow and a solenoid to make up the difference increase the reaction time available to the diver in the event of the an electronic failure?
I know how long an MCCR loop takes to decay (between O2 additions) and how long that gives the diver to correct the situation. How much reaction time does the diver get to deal with the O2 decay in the loop when an eCCR fails? (I've never dived eCCR but my guess is, not long. Please correct me if I'm wrong.)
In this configuration would the diver have longer to spot that the loop O2 was decaying owing to eCCR failure and if the orifice blocked the solenoid would inject more often?
