This is great news, Robert, regarding the creation of the FCBeamExtensionMod.
I had the feeling, as you said, that the Left/Right Horizontal offset had an impact somehow/somewhere and your explanation makes sense.
Looking foward to RGP Lua v0.63 :)
¯\_(ツ)_/¯

They affect the angle of the beam by starting the beam as if it started at the horizontal offset but then the beam only shows starting/ending where it intersects the beginning and ending stems. This could actually be useful in some tight spacing situations (also tremolos!), but controlling it is going to be mostly guesswork and trial and error. (I actually now wish Finale's UI could do it, just to make figuring it out easier.)

But good news: I recently realized it was missing and have created it for v0.63, which is the next release of RGP Lua.

Launch any of the html pages in your browser, and you'll immediately be looking at the full doxygen pages updated with all the upcoming attractions for 0.63 in the PDK Framework.

>>> I'm fairly certain that these are calculated values provided by Finale so you don't have to constantly recalc them for yourself. (Same with the clef value on FCNoteEntry.) I don't really know why they are writable. That was done long before I got to the code base. Any new values you write will be retained for the life of the FCNoteEntry instance, but they will not be saved.

>>> To copy TGTools Easy Tremolos you need to modify the Duration property and add an invisible tuplet. So, for example, to turn 2 consecutive quarters into a half-note tremolo with three beams, you would change the Duration of each note from QUARTER_NOTE to NOTE_32ND. Then you would add a new invisible tuplet to the first one that is 2 32nds in the time of 2 quarters. After the FCNoteEntry is saved, the next time you retrieve it the MeasurePos and ActualDuration properties will have been updated.

>>> I don't at this moment recall how much Jari's documentation says about TGFs. The PDK Framework mostly hides them from Lua scripters, but it's a pretty important concept for working with note entries. Entries always come out of a TGF, which is an array of entries for a single layer in a single measure. To save an entry, you have to save the entire TGF. This can lead to possibly unexpected behavior, for example:
>>>
>>> for e in eachentrysaved(region) do
>>> e.Duration = e.Duration / 2
>>> break
>>> end
>>>
>>> This would appear to halve the first entry in a region, but in fact the entry won't be saved because you broke out of the loop. To save the entry, the loop *must complete*. (You can see for yourself how eachentrysaved works, because I've posted all the built-in iterator functions to the lua-source <https://github.com/finale-lua/lua-source> repository. Or you can fish it out of the jwlua binary for yourself, like I did originally.)
