The po2 argument of that function was never meant to be any measured or calculated value, it is the set-point of the rebreather and as long as there is no sensor data that is the only source of knowledge about what the diver as actually breathing. If there is sensor data then fine, that is better but if not (as the diver did not log it or we are planning a dive) then our universal “determine partial pressures” function should work based on set point and dillutant gas mix. And if you want to rely on that dive computer enum then make sure it gets set properly.
