As a slight response to the original question - and possibly something that will only be understood by people who already know how to do NDB tracking - I remember an instructor saying,
"Only look at the top half of the instrument. One end of the needle will be in there - either the pointed (correct) end or the blunt (wrong) end.
Look at the bearing suggested by the needle - is it what you want? If the answer is "No", then turn. Assuming "correct" end of needle turn the correct (same) way (if it's right of what you want, turn right - if it's pointing left of what you want, turn left).
If it's the "wrong" end of the needle turn the "wrong" way. If it points left, turn right."
How much to turn by is another question
