How about the unusual case of more than 2l/min O2 consumption? Yes, very unlikely. Especially without the user noticing the odd conditions...
The solenoid is in paralel of a KISS orifice, so total flowrate is about 2.8 ltr/min I guess. Your body cannot metabolized such a oxygène quantity.
No idea if it is sufficient in case of really fast ascent.
Always nice to read very creative and innovative rebreather divers
