Slim, I don't mind at all, I think it sheds some light on his success or lack thereof. The best selling of my books is an alternate history, "1910: War in the Pacific." I've sold 740 physical copies (paperback and electronic) and 461,438 page reads. This is functionally equivalent to 1503 books, for a total of 2243 sold. The book has 170 reviews, so 13 reviews for each sale. Applied to Lloyd's 600ish reviews that translates to 7800 total sales.
Translating Amazon's sales rank number into units sold is notoriously difficult, calculating profits is even worse. In Lloyd's case the printing costs are probably taking a big bite out of his profits.
Speaking of costs, what the hell did he need fundraiser for? The printing and publishing costs at Amazon are charged when a book sells. If he hired some one to edit it doesn't show in the final product.
