I deeply respect what has transpired with the development of the Dorico music notation and performance software over the past two years or so. So many great advances! However, I wrote a post with a request a while ago in regards to the need for more documentation on Expression maps. You said in reply that there was no such document ready or one planned at this time and that the Expression maps feature set was not complete yet. You added some explanations on the forum about a few of these matters (which were appreciated) but some of it was a bit confusing for me or presumed some prior knowledge I did not have.
Would it not save time to write a document that clears up some of the more important questions rather than you having to read and reply to all of this stuff on the forum which is also itself partly generated in the first place by the lack of fuller documentation?
