    I should add:  I'm teaching a course to undergrads, where celestial navigation is only one part of more material.   I use the equal altitude method in an assignment where they observe (from a stationary position) the altitude of the sun over the course of a day and extract latitude and longitude using equal altitudes.     I hate to say it, but the mathematical preparation of some of the students is quite poor.

    Oh, yes, totally understood.   It's a teaching tool

    Relative to equal altitudes, I'll issue my standard warning that observer
    motion and declination change need to be considered.

    I may not live long enough for the popular myth that the simple averaging
    of times of observed equal altitudes is dispelled.
