If I am reading your post right, you are using the length of the target instead of the height, to estimate the range. I don't see this as practical, because you will not be able to rely on having the target at an AoB of 90 deg., and without map contacts, will not be able to accurately estimate the AoB. This would add a additional source of error, and would be less reliable than just using the stadimeter and some sort of correction for the hull down effect.

If you set up your test with ships only at a 90 deg. AoB, you might get good estimates, but how could you replicate this in a realistic scenario?

In RL, they just had to accept the limitations of the stadimeter until RADAR came along. Skillful plotting and "fairing the plot" helped. In any case I do not consider range estimates beyond 5,000 yds. or so, to be very reliable in this game.
