That's the best "gum summary" I've ever read!
(probably because it is exactly how I approach it... Except for the note-taking, of course)

For stock gum/pigment solutions I do as you describe, in case of adding
pigment from tubes I use 1 part dichromate to 1 part of gum + the pigment.
(I tend to use strong pigments in small amounts, therefore I assume/accept
both working styles as being equivalent.) The pigment amnt, exposure time,
dichromate strength, development time/method all will change relative to
each other and most importantly to your goal for that particular layer.
It's not rocket science at all; just try to establish "the feel" by
experimenting (changing only one variable at a time) and good note taking.
Don't try to work by numbers only, it's counterproductive and boring
(you'll understand what I mean if you try to calibrate gum). Try to work
more like a painter, you'll see that it starts to become (or, better, the
general direction of your working style will be) second nature after
some(!) experience. ;) (Not that I'm implying I have lots of
