Let's be very clear on this: the SINGLE BIGGEST UNCERTAINTY in standard line of position celestial navigation (or any celestial navigation that is equivalent to LOP celestial) is the uncertainty of the horizon --the variability of dip. ... And there is nothing that can be done about this. It can be interesting (and "fun" as you said a while back) to observe this variability to get some real sense of how large the effect is. But "solving" this problem is a wild goose chase. And it's a goose that the developers of navigational methods have been chasing for over 200 years!
