I'm going with a suggestion of 4x/week (one chapter each). If this doesn't work, the aim will be twice or three times a week.
My current planned schedule is M/W in the morning and Fri/Saturday in the evening. Obviously, for those who prefer to read less often, pick a couple days and there'll be a couple chapters waiting, with any luck.
Chapter 9 should be out shortly, 10-12 are queued (and I'll get 13-16 in the system shortly).
Thank you to everyone who's taken the time to write to me!
