"I would like to know if he is right. Did the original LD tables always include the Sun when it is within roughly 40° to 120° range? And is this the best practise today?
As contextual information I include here below my LD tables and charts from 25th to 30th May 2023. You notice that the Sun is only included on 25th May"

I have been reading your posts about your tables since you started, and from the beginning I have thought, 'geez, this guy has no idea what he's doing', but I didn't bother you about it. I assumed you would learn...

But wow. Just wow. What kind of rock have you been living under that you don't have the Sun in your lunar distance tables for every day that it is observable? Haven't you even bothered to look at other resources (like the tables on my website) or a sample of historical almanacs? And no, your suggested range for the Sun (40° to 120°) is still not correct. 

Anyone looking for celestial navigation data should proceed very carefully when using thenauticalalmanac.com because it is generated by people who understand computation but not necessarily navigation, and this debacle is an excellent example of the problem. As for lunar distance tables, of course, there are many other options, including the tables on my website which have been available with numerous selectable options for nearly twenty years: lunar distance tables.

A reminder for anyone interested in lunars: my workshop on Lunars is scheduled at the Treworgy Planetarium at Mystic Seaport Museum June 10-11. Info and registration here. The dates are not random. On Saturday, June 10, the Moon will be "in distance" just about 90° from the Sun. Historically significant as one of the most popular days to shoot lunars and still relevant on some mathematical grounds today.
