The problem is, low speed micromanagement is good for learning, but not casual watching unless it cuts slow parts often or is heavily edited. I find the send/recall rather distasteful to execute, but don't have a conceptual problem with it and will use it if I feel like I need it. I don't think it's fun viewing material to watch someone spend their first 30 minutes on send-recall improvement to tons of nations at once as say an Italian minor, or to watch someone perfect-micro their colonists via send/recall spam as a native council because 10 growth per colonist >> settler chance at low travel times (and god help you if you get 100% envoy travel time reduction and want to micro colonies, it'll be the entire gameplay for a long time).
So, anybody doing a video has to strike some kind of balance. OP's comments rub me the wrong way similarly in some ways, but I can understand if someone who wants to play the game casualty wishes to see rundowns of other more experienced players similarly limiting themselves.
The implementation of this game is uneven enough that wrt a given choice people are going to draw lines on different sides of it often. I find that debate, or even bothering to distinguish between "exploit" and "strong tactic" when both fall inside the bounds of rules, to be pointless. OP should IMO just go down the list of names he's seen here and see if there's a commentary style he likes. Years of annoying finger pointing wrt exploits in Madden, Civ, and elsewhere in addition to here have shown me that no good comes of people coughing up arbitrary and almost always self-inconsistent definitions of "exploit" that turn into moving targets week to week. Usage of that term suggests naivety at BEST.
Higher speeds or force speeds are definitely costly though. Running Bosnia alongside Paradogs on Ethiopia in MP mostly at speed 3 (we went down to 2 in the end which helped notably with progress rate) I was pathetically behind what I did with Orissa when I could pause/plan/stop even though I also streamed the latter, which is still worse than low-speed micromanagement with more focus. Sure, had I been a bit luckier with my mid-game alliance pick I could have maybe conquered all of Europe rather than leaving a small chunk of France, Scandinavia, and an intact Russia, but it would never have been an elite game even then. Part of that is due to my skill limitation, but losing time while thinking of what to do next is very damaging also and really delays the snowball.
