The short release period gives off "For a limited time only!" vibes, a scummy way to entice people to buy something now because they might not be able to later. It's also unclear that the notes even add value, they're described as "raw unfiltered chapter-by-chapter notes". Are they just random thoughts? Are they a better version of the chapters they line up with? Are they a companion to the book (the notes elaborating on the parts this author found to be too brief)? Are they responses to the contents? You don't know, until you spend more than the cost of the not-actually-bloated book that they cover.

Yes, but it's not clear at all that this $25 limited-time-only set of notes actually does that, and they cost more than a book that is decidedly not bloated (it's 100 pages, 33 chapters, and each chapter is quite short).
