Andrew: This whole thread has been fascinating to me. Sorry I have not had the time to participate earlier.
Since I created the spreadsheet, one might logically ask which fret placement system I use. The answer is, none of the above. I have set my frets empirically, according to what sounds good to me. I just measured my 55 cm 7-course, the instrument I play most frequently, and got the following numbers (nearest half mm), with indications in parentheses as to which historical temperament most closely matches that value: 1st, 2.85 cm (Kepler tastino) 2nd, 5.75 (Aron meantone) 3rd, 8.7 (Equal temperament!) 4th, 10.95 (Aron meantone/both Mersenne) 5th, 13.7 (both Mersenne/Werckmeister) 6th, 15.85 (Silbermann 1/6th comma) 7th, 18.1 (Aron meantone) 8th 20.05 (Silbermann 1/6th comma) Keep in mind that the fret placement interacts strongly with how you set the piteh intervals between the strings in determining the frequency generated by any given string/fret combination, so that you cannot just tune each string off an equal-tempered electronic box and expect any historical temperament to sound good. For example, I take a reference pitch for the 6th course and tune the 4th course/2nd fret to an exact octave above that, so the 2nd fret placement determines the 6th/4th course interval. I then tune the 2nd course 3rd fret from the open 4th course (maybe not quite so exactly), so the 6th/2nd course interval is determined by the placement of both the 2nd and 3rd frets. I am kind of out of time, but I will try to continue this evening.
