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.
Interesting reading if only for the history of it. Did not manage to pick anything that would be applicable to today's markets unfortunately. I would suggest that people interested in tape reading continue looking.
STOP: dont buy this book!!!!! its a poor scan of the original classic. They didnt even bother to spell check what the computer has transcribed. Its unreadable. The grammar is even worse. I cant believe Amazon allows them to sell such a poor copy of a great book. My advice is to rather download the original off the internet on pdf for free. this book is unreadable.
