There's a lot of good info in this book, lots of stuff to provoke thought, and it is presented in a very simple and easy to understand format that communicates the points well - like a military training manual (but with a little more humour)
Unfortunately, it tends to rehash subjects discussed in Speed Secrets and Inner Speed Secrets, which means that the amount of new material (for owners of the other two) is roughly half of what is already a pretty thin book.
Between the three books, there is one outstanding book in there. If Mr Bentley writes another installment (as he threatens to do in this book) I hope he compliles all his books into one big one, adds a couple of new chapters to cover whatever new material he wants to add, and then edits it into a coherent whole.
