I just love the idea that reading little numbers on an electronic calculator is bad airmanship. Apparently reading smaller numbers on a whizz wheel is not!
Get with the times, encourage common sense, if someone is fast and safe using any technique, then rather than "throwing stuff into the baggage hold" take some notes yourself, you might learn something!
