Query: How does this rate 4.5 stars on average?

I bought this book with my first guitar in an effort to pick up some basics on learning guitar and all I can say is that this book is VERY strange. Has a chapter on how to cut your fingernails the right length for playing, and if you plan on playing for friends pick something easy and don't say things like "I'm not that good yet, or I might make some mistakes" (thanks for the genious advice captain obvious"). This book is written in such a remedial fashion that my girlfriend and I couldn't help buy laughing after many of the sections. One section uses "practise" and "practice" interchangeably approximately 8 times on one page. Anyone who rated this 4+ stars has to be on the payroll.
