Continuing the discussion from How to find text in ellipses:
After reflecting some more on that that ten-year-old post, I took a closer look at DN 3 and DN 4.
The description of the gradual training in DN 2 begins at DN 2:40.1 and continues through to some point before DN2:99.1
What I completely missed on my first reading of DN 3 is that this whole thing is repeated from DN 3:2.2.2 to… some point. I only went and looked for it because I’d seen Bhante @sujato mention it in writing more than once or twice.
Likewise in DN 4 it begins from DN4:23.2. I missed this on first reading too, until I went back to seek it out. But even now I’m not sure where exactly the repeated section ends, in part because there is some slight variation in the exact wording of the ending, but mostly just because the abbreviation is so aggressive.
I’m sure I’ll find the same thing in DN 5 through, what, DN 13? But my uncertainty about where and how the expanded peyyala should end shows that I certainly don’t have the skills yet to start on this project, even for this low-hanging fruit of peyyala-expansion.
Editing to add: since I kept this in Q&A, I may as well make my question explicit: where exactly does the repeated text end, in each of these three suttas, DN 2 through 4?
