Simple, I read the wn so pacing may be different in the novel, but lets take this as base value.
If I imagine what would be in a manga chapter, and then I chop the manga in 2 or 3 parts for a chapter, it would be the better part of 6 months of literally nothing happening, and there would be no manga going forward.
I love these little parts of the story, but if the story is chopped in 2-3 parts a chapter they would be hellish to read while its new.
If you want an example from a manga thats not butchered to hell and back, look at berserks first 3 volumes.
They went hard and fast for the first 3 volumes to get people invested, so when they went and did the slower aspects those people would still be well invested, and that was a non burchard monthly manga. now imagine the first few chapters of the golden age arc cut into 1/3 or 1/6ths (berserk chapters were a bit long) and space that out over months and tell me if thats something, even if you were well invested, you would put up with.
