in theory I agree with your list, but I find that Mannequins, in breaking most of these rules, have made a much more generative (ugh, that word) manual than any of the other Eurorack manuals I’ve read, while still remaining plenty useful. The W/ manual even turned me on to the music of Dakim as part of a useful use suggestion.
I like the Max/MSP help patches as an example of the potential software documentation has. (the lack of a thorough-going general manual bothers me, though)
Ableton’s manual, I have to say, has been the most pleasant surprise to read from; the explanation of what they’ve modeled each piece after, from the session view down to the device parameters is clear, concise and includes plenty of inspiration in the form of asides.
