Basically for the "Name displaying model" and "notation" field, you have to figure out what rank is the note that has to be spelled there; in 2nd inversion, the 3rd note of the chord is the root, etc... and use N1 for note rank 1, etc...

Then for the "Root rank", the most mind-boggling of them all, even when looking at graphics, the numbers paired to each chord's name determine
"what's the rank of the note, in the chord for which you're entering information, which is the root note of the just-written inversion?

Then for "is a voicing/inversion of fields, the numbers just represent the rank in which the inversions will be displayed when you request the just-written chord.
Not that complicated, but you have to remind you're handling data for multiple possible chord requests, accross multiple chords' tables...
cause fo course once the chord is entered, you have to go back to the others and add the info too :)
