Setting power level at degree output when turning up a WL

After having successfully set the power level for a WL at a node degree output, the controller just sleeps for 60 seconds before changing control mode from Power to GainLoss and moving on to the next node. This seems very inefficient. Doesn't it mean that turning up a wavelength going through e.g. 10 nodes will take at least 10 minutes (+ the time for turning up the transponders, etc.). The maximum time to achieve channel power target for a node degree according to the OpenROADM MSA spec is 12 seconds. Would it not be possible to get confirmation from the node (through NETCONF) when the power target has been achieved?
