OK, I haven't got time to go through everything in detail just now but I did have a look at the data for the first concert instrument.
If this is your actual measurements,
I may have lead you slightly astray with all the fret to fret measurements (it IS a rabbit hole). The only reason that I took you down this hole is because you can't make initial accurate measurements using either the nut or the saddle.
To start with they HAVE to be excluded as they are likely wrong until we can independently confirm that they are correct.
The true zero/zero point on a fretted instrument is actually the centre of the 12th fret. I know that someone else mention the nut as the zero point and I let it go and if you KNOW that the nut is right then it does work but we don't know that yet. Also, if we do compensate the nut (which is a useful thing to do sometimes) then the nut is again completely unreliable as a zero/zero point.
So, keep on trying different (shorter than 380mm) scale lengths in the stewmac calculator until the stewmac data aligns with the MEASURED data (fret 1 to 12, fret 1 to 16). WHEN that data ALIGNS, THEN you will know the true scale length for the FRETS.
THEN, and only then can you measure to the nut and saddle from the centre of the 12th fret and get useful measurements.
If this is your actual measurements,
, then the actual scale length is shorter than 380mm although I can't work it out just now.*Ctr of 1st to 12th frets@ 166.5mm = Ctr 1st to 16th frets@ 205mm =
