Yeah, I have no idea how other quests handle combat if they don't do daily or multi-daily updates. How do they keep the pacing feeling good?
Now I know I'm a bit late for this (had a test today) but I figured I'll add my two cents.
Questing in general requires the QM to balance between control over the narrative (and the characters in it) and player agency.
This is done in various ways and the needle can always bend to one side or the other without to much trouble as befitting the QM habits writing style and motivation.
This quest is deep on the player agency side as we got a lot of control over what, how, and when things are done its also more a mechanical quest then a narrative one *looks at giant wall of text on various aspect of the system*.
By itself this isn't necessarily bad nor is it necessarily a good thing because everything has draw backs and advantages.
A big thing with this quest is that without a fast pace engaging in the combat in this setting would be a pain in the ass and while the session turns would be better they would still suffer somewhat (with the average writing pace we would have reached our current point next year if we were lucky).
Its why most quest's that have high player agency (in combat) and use a round per post (or more communally 2-4 rounds per post) have a QM that tries to put the effort in to do daily (or every 48 hours) uploads for those specific parts.
Now again this isn't necessarily bad and honestly this suits your writing pace and style so the drawbacks are mitigated, not all of them of course mechanical complexity can discourage people from creating plans or participating because they don't understand the system (although in experience there is almost always one or two players that jell with the system and are happy to convert other players ideas into mechanical terms).
Of course, while a high writing rate is very much welcome a high posting rate can also have draw backs, mostly consisting of the fact that most people don't spend 24/7 on the sight and that time zones are a thing, so a fast moving thread requires a lot of effort to keep up with and when you get to the point when there less then 20 hours between the vote being opened to the vote being closed a lot of people miss out on the chance to post push their own idea (if they are even noticed it soon enough to vote, I know that I woke up to double updates which meant I had no chance to vote in the first one) which can hurt active engagement.
In the end everything has a drawback so you really need to pick the one you can work with.
