Hi Padowan
This is correct if you have ramped up your setpoint to 1.6, but is not symptomatic of O2 RBs per se.
If you use the unit as an O2 RB, after say a complete electronics failure, where you are flying by the seat of your lungs and running minimum loop volume and manually adding O2, then the drop will be as a result of O2 metabolisation.
However I do see your reasoning, my point of caution is that it has to be said that one of the earlier fatalities on the unit is believed to have been from running the unit at high PPO2 on deco resulting in an ox tox.
