Don't get distracted by the numbers, just ake and reduce one sight on one object. Jared, I wish you would give us an example. I don't understand your explanation. For example, it's unclear to me what you mean by "position". Is it the observer's position or the body's geographical position (the point on Earth with that body at the zenith)? That's one of the several things I didn't get. Just pretend I'm from Missouri and show me your method with a fully worked example.
