An observation about outbound NDB tracking from my IR days. One of the NDB approaches that I used to practice, had the NDB at the IAF, 4.2 nm from the threshold. I always found outbound tracking very difficult, until one day my instructor suggested "Once you have tracked to the NDB and have station passage, don't change your heading. You'll be close enough to the runway when you reach your missed approach time." It worked very well.
