Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
First third kind of slow about how this island nation came to be. The second third more about the politics and language. Interesting to a degree but I had to plow through this part. The third section was about the people, places and things to do. What I as a tourist would want to know. Definitely worth the buy.
