Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
I have only listened to perhaps 2/3rds as yet, but I find the material excellent. The author uses excellent into insights & explains in easy to understand terms. He brings to life the journey of the children of Israel's journey and gives a larger than life appreciation of Moses & his trials with not only Pharoah, but the flock in his care, as well. I have gained a greater insight & appreciation of the book of Exodus & now wish to purchase more of the authors works on the Tanakh.
