Actually, as a reader, I would prefer book publishers to know what gets read in their books and what doesn't. Likewise, I would like to know that information as a reader. There've been countless times when I purchased a heavily advertised (well reviewed) book, only to find out that it was worthless piece of ... Anyways, those books weren't written for me; they repeated the same stuff over and over and over again. One example - Good to Great. The first chapter is good, so is the second (maybe). Everything afterwards is just a repetition of the same concept. If I could see ahead of time that most readers stop reading the book 20% in, I'd make my assumptions and not even bother to try to get through it. Likewise, there are books where the first chapters are quite tedious to read, but the rest are great. If, while reading chapter 1, I could see that most people struggled but then persisted and loved the book, that might encourage me to get going. Just my 2 cents.
