To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I was very disappointed by this book which reads like a series of poorly transcripted talks rather than a serious historical study. The subject is touched upon at a very superficial level and the author appears to rely on paragraphs from other writers to make significant points. In addition the language is tortuous and as always these days full of typos and poor grammar. I guess this book could have been improved by better proof reading, but overall I would not bother with this book. I gave up after a couple of chapters which is the clearest evidence of my disappointment
