Chris,

Thank you for the update. The lunars tab is the part that stands out:
very few modern programs attempt lunar distances at all.

Which clearing method does the solver use, Borda, Young, or a rigorous
iterative solution? And how are refraction and parallax treated when
either body is low?

Does the stated uncertainty propagate the amplification from distance
error to clock error? The Moon moves about 33 arcminutes per hour
relative to the stars, so 1 arcminute of error in the cleared distance
is roughly 1.8 minutes of time, about 27 arcminutes of longitude at the
equator. A sigma shown in seconds of time looks reassuring; the same
figure expressed in miles would tell the user more.
