That certainly is not the way the Navy's manuals do it. The duration and
prep does depend on when you dived the machine last. If it's been some
time, then I can see that you might want to strip down and completely
overhaul the machine, but for a week of diving (3-6 hrs/day in the water) I
will spend at least 6 hours prior to going on the trip, but only 30-45 mins
each day during the trip.

This doesn't make sense. The 15/16 are designed to be flown manually and
taught that way. Flooding the electronics - due to leaving the set-screw
open - is possible, but means that the pre-dive checks were not followed. I
believe that this is the way the US Navy floods happened. But that still
should not kill you - see my post to the rebreather list re Dive Log:
Catalina 7/27

Yeah, from a noted "expert" on electronic 'breathers ;-)
