I'm trying to create a writing schedule. My plan is to write a chapter at a time and draft intially by hand. Then, once the chapter is complete, type up the second draft of the completed chapter on my laptop before moving onto the next part of the novel. My question is, how much does your word count increase by going into the second draft? I'm planning to write 2k for each chapter during the first draft, but I'm not sure how long they second draft will end up being. It's only an issue because I'm trying to create a schedule along with self-imposed deadlines as not to fall behind. I'm just not sure what to expect in terms of time and word count.
