There is no sensor data in that log, only setpoint information at the start, when the setpoint changes during the descent and before surfacing. > That said, I think setpoint values are still interesting to see, to > validate how well the controller did manage to try to keep the o2 close > to the setpoint. > > > Attached is the last iteration I did of the sensors patch.
