Instead of calling this book "Repeatability", they should have just labelled it "Continuity": it's really not a huge surprising leap that continuously practising best practices over having only one inspired moment leads to the best results.
All of the points in the book are valid, and the case studies are well researches (the companies either seem either over-analysed in the literature or beyond esoteric); however, it's just hard to see the need for all of it. (Suggestions like continuing to encourage learning at all levels in your organisation is just common sense, for example.)
The most useful section is a page at the end of each chapter with a list of questions to ask yourself every few months.
