Did you read the preface in the book. It isn't really meant for advanced users, but people new to the OS. While the methods describe are not the most optimal, they are easy to follow and understand.

I think that is the point of it really. Once the reader has built a base of understanding they can dig out the most optimal way to do something and comprehend what it is that they are doing and why.
