I would like to add one point, and ask Scott to comment.
While taking a Winter Alpinism group course in Chamonix, our instructors would emphasize that moving efficiently in the mountain most of the times was about not losing time trying to get things perfect, but rather making things work safely. As an example, it would be inneficient to store your ice axe on the backpack loops when you won’t need it for a while (what would require taking off your backpack), where one example of efficient choice would be to just pass it inside the backpack’s shoulder strap, “guide style”, avoiding loss of time.
