the opinion about the solenoid failing from non use is silly (IMHO)

Who cares what my PO2 is, as long its ABOVE what I have told my computer I am diving? So what if it bounces between 1.3 and 1.1 as long as it doesnt go below 1.1? It adds a tiny bit of DCS margin.

Hi Ron, I did not voice an "opinion" that the solenoid would fail from lack of use, only the idea that it might, as do other pcs of dive gear that are not used frequently, a perfectly reasonable thing to put out there, IMHO. I think that's what Mike meant too.

As for SP control, I do care about the accuracy of it as while it may be a hedge against DCI to have periods of .2 above, it's also additional O2 exposure. I take long trips, usually at least 2 weeks, and find myself pushing up to and sometimes over the OTU/CNS limits, so I plan my repet dives around these numbers and would prefer to know as exactly as I can what my O2 exposure is...

I think the leaky KISS valve stories shows how valuable a HUD is and how easily complacency can effect even KISS divers, and so the plot thickens. E or M CCR, it is your monitoring devices and habits that will keep you alive and has much less to do with whether the device is purely M or E CCR.
