@Stoicic I also get where you're coming from but the publisher is already splitting the chapters, and you want to further split it so you could release a part of it earlier by a few hours/days earlier?
Just release it when you're done, no need to enable readers without a lick of patience.
Reminds me of my friend back in matriculation college. his mom force him to join the science program in the college when he's not interested.
So he purposely flunk the tests in the first semester and have to drop out of college.
