One of the "weak" points of a manual system is you have to add a fair bit of o2 on the ascent if you want to maintain a good po2. If you or your buddy are in trouble and you have your hands full doing other stuff a manual system could put you in danger(its very difficult to do a controlled bouyant lift on an unconcious diver and maintain your po2 manually) For me this is where the parachute system comes into play.......so
run the unit on the orifice and have the electronics as a back-up
slightly off thread but my belief is that the reason why MCCr's have a good safety record is the "mindset" they instill in the diver. Adding auto functions may deteriorate that mindset!
