I don't see how the pure act of setting the timer manually further helps me learning the basic process (which I think I have already burned into my long term memory after all the test runs). I don't see how taking notes by hand on paper in contrast to having the computer record them for me does help me in learning the stuff better. I don't think having an process timer that rings an alarm when it's time to move paper to the next tray will stop me from knowing the process of developing the print. Whnever I try something new, I do that fully manually at first anyway.
Then you're fine. You don't need our affirmation.
