It's just that I think it needs an editor to go through and slash and burn some of The Bad Parts sections. Some discussion of that is needed, but I suspect the author used his expert status to intimidate his editor into making poor choices on what to cut.
Like the author said, This book is small, but it is dense. It is very hard to understand some pages in the first read. I read every pages at least 3 times, some pages more than 10 times to get the idea fully. But the effort definitely got rewarded.
