A riding buddy also made an observation... Decide which foot you'd rather be the dominant un-clipper. Unclip that one each stop until it is total routine. Practice with the other one of course, but make one the primary foot, the expert at un-clipping. Ex: I prefer to push off with my left foot, so I un-clip my right each stop to avoid having to remount the left (efficiency) and to make it a decisionless procedure.
