Or, and hear me out on this, but you could leapfrog and do chapters 31 to 40. Then when original group releases chapter 30 (some time next year), you just
immediately upload the ten chapters which were ready and waiting, since you had already finished them beforehand.
There's no duplicate work, and the series gets brought that much closer to completion. Win-win.
Other group leader seemed uninterested in working with you, so leapfrogging may be the best way to move things along.
Just a thought.
