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.
Josh Bryant always presents 5 star information. My poor star rating reflects the fact that formatting for Kindle is so messed up, that's hard to know what the program looks like....sentences intermingled, sets and reps not near the exercise. Not really readable. When the book is re-formatted to be readable on Kindle, I'm sure I'll be able to change my review to 5-stars.
