"Does anyone make regular use of the Lunar Distance Tables that are available via thenauticalalmanac.com? I've been using the Stark Tables, and it seems like the Lunar Distance Tables above effectively cut the work in half by eliminating the need to calculate the hourly distances from scratch."

I checked that table at five random times in 2025. The table does not state its time scale, but I assumed UT1. At each time I checked Moon GHA and declination, as well as the lunar distance of one body selected at random. Every value was perfect at the 0.1′ precision of the table. 

For TT-UT1 I used the predictions in IERS bulletin A. It actually gives UT1-UTC, but from that you can calculate TT-UT1, which to sufficient precision was 69.1 s for all test points. The values in the table (at the top of each page) were different by a tenth or two. A 0.2 s discrepancy in TT-UT1 corresponds to 0.05′ in GHA.

You can't expect "good to a tenth" with the Stark method since it calculates geocentric distance from two GHAs and two declinations, each extracted from the Almanac and rounded to the nearest tenth. Furthermore, Sun GHA is adjusted to eliminate a v correction.
