Justin -- a thought for your cogitation. Right now, you've got a buffer, so if you get blocked or overloaded in other areas of your life, you won't freak out, worrying that you've got nothing to share with your avid (rabid) readers. I think that, for me, not having that buffer could cause me real problems, if I felt I had to turn out product, even if the work wasn't going so well at some point. I know I've pushed you for the next chapter myself, but I want you to do what's best for your story, and for your personal comfort level. Once chapter a week will keep your audience engaged. Beyond that, consider what will work best for you.
