I was following the release of this book and will probably buy it shortly. I think the reason that a lot of people are being so critical is that it's UX. I work in UX and everyone is (or thinks they are) a UX "designer". I looked at your sample pages and web site and thought I could learn some things from you. I also thought it looked great, so I don't think you have anything to worry about.
No one is going to do things exactly the same and your book doesn't come-off as being a forceful entity on rulesets, which is nice.
I would also like to see some other pricing options - mostly because I want the book and PSDs only, but I don't see anything wrong with your pricing model. It scared me at first but I didn't see/notice all of the extras that you had for sale with the book.
Anyhow, good luck, I can tell you spent a lot of time putting the material together. This is a tough crowd but in the end most criticism, even if harsh, will hopefully be constructive.
Enjoy the sales and focus on the real UX designers/developers ;)
Also, the data could drop low on the 31st because not all months have 31 days so when tickets are distributed evenly over months, that day does not easily match up with 28 (being the definite last day of a month)...then 29, 30 and finally 31 being the least used.
That was actually compensated for in the "Correcting for more frequent dates" section. The first graph of that section shows what you would expect the distribution to look like, since not all months have the same number of days.
The following graphs are based on variation from that expectation.
But the analysis did not account for the variable number of weekend/weekday days on each day of the month. I don't know how meaningful this is, but it would be worth it to inspect this separately and then weigh it in if needed.
