Trying to decide how much time to spend on James I bio.

I'm working on an annotated edition of Rushworth. Much of the annotation work is in the form of biogrpahies of some 300 of the key figures; biographies that are in turn heavily annotated. My problem is with the "major" biographies, and in particular that of James VI and I. It's extensive--about 20000 words--but I can't decide how much more effort to put into the notes. I already have 35 notes, but it needs 110 more.

Arguments on the side of fewer notes:
-- Most of the material is very well known.
-- The notes tend to be viral. If I include a bio of Mary Queen of Scots, that's another 100+ notes.

Arguments on the side of more notes:
-- The notes are the real value. The text already exists on the web.
-- I have a lot of flexibility: I can write 100 words on Mary Q. of S., or 10000.
-- Many of the notes are already done, and new ones can probably be reused.

OK, I've convinced myself: Another couple of weekends on James I it is.
