On the practical side, I’d suggest against super long chapters too. I’ve tried that on my potter fanfic years ago, reorganized/rewrote thinking it was a “good thing” with my highest being like 107k… nope! Not only did I lose some details in that consolidation, I also lost focus to the chapter too. Small details/scenes were now one/two sentences in basically a wall of text. (Which it became as FFN.net somehow seemingly lost all my carriage returns, so it was one big “blob”; and a fast re-insert of them is how I uncovered FFN’s new 65k max per chapter limit.)
I’m still pulling that 107k old chapter apart right now with my “rewrite” … though I’ve now got at least 121 in its place, which is probably close to 1M words itself as I now hover around the 6-7k words per chapter average, and if the chapter nears the 10kword mark, I seek to break it up. Even in my Jefferey episodic story, I’ll effectively do “part 1” and “part 2”.
