The maximum my program allows is 300 pages, but I hope to write no more than 200 pages. I figure if I set my sights on 150 (the minimum), I have room to expand if needed. I'm hoping this limit also will help discipline me. After all, most books I read could stand to be shorter (that is, better edited), not longer.
My current total of 27 pages includes a 5-page introduction, which I project will eventually become 10 pages, but it's almost impossible to fully write an introduction of a book I'm still in the process of writing. It is like trying to introduce someone you haven't met yet :) So, I'll settle for a inchoate half-intro for now.
The number 27 additionally includes 22 pages of my first chapter, which has four major sections, three of which are essentially complete. I hope to finish the final section (which will run 10-15 pages) in the next two days. But I'm not includes estimates from the final section at the moment because the draft is so rough (more of a "zero draft" than a first draft).
Then, I'll spend the rest of December (with breaks for Christmas and New Year's) tightening, making connections, weaving in thematic material, etc.
Hopefully in early January, I can transition into drafting, writing, and editing chapter two -- with the goal of starting chapter three by early February.
We'll see.
