10 minutes is a bit far fetched, if you only follow a single route or two, then you're cutting content for yourself. Play all routes if you want more content.
Was going to say something along these lines. The update was around 20 minutes for me... but I also deliberately cut off certain branches via my choices so I know there's almost certainly content I'm not seeing (and it doesn't help that I tend to speed-read, so I go through dialogue faster than most people).
That'll always be the problem with games that allow for player choice, though - if an update has like five new scenes, but player choices mean someone's only going to see one of those scenes, it can feel like a really short update for players even when it really isn't. There really isn't anything a dev can do about that other than focus on one path each update to the exclusion of the others (but when dev's do that people complain about updates being "worthless" if their preferred path isn't the one being updated, so it's kind of no-win).
But I'd vastly prefer "short" updates as a thing rather than just sticking to linear kinetic novels where you get 100% of the content every update but have literally no say in the story. Choice is good, multiple options and paths are good - but there's always a price to be paid (in development time, effort, and how much an individual player gets out of any given update).
