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 analyzes reviews to verify trustworthiness.
I like all of mr Rundell’s books, but like like all historical fiction writers, I expect their facts to be very very accurate; an example in the Commanche conflict book is the reference to Gabe speaking Algonquian to the Comanche and they understand ( he is speaking Shoshone which is Uto-Aztecan) which the Comanche would understand possibly since the Comanche and Shoshone are offshoots of each other. NOT Algonquian!!!
