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 liked this book. I would like it to have more actionable steps in it. Like some samples gardens I could try with a small space and complete instructions. I find I'm just having to pick out pieces here and there. But overall it's pretty good.
