It is not the same book as phelps read I don't know, but most similar book for visualization and relaxation are any of jose silva books.

I typed progressive relaxation into amazon, and it looks like the book is written by a guy called Dietmar Ohm

It3called progressive muscle relaxation technique. We use this in psychotherapy

theres plenty of techniques, but basically you have to study the real scenario and elements that your visualisation will be based on, then you start by adding those elements to your mental practice until you perceive them to be real ( taste, smell, etc ) and you will have to create a 'movie clip' that you loop over and over until it feels absolutely real in your mental practice.

That free will an visualisation will actually help the flow of that much more

You actually want some parts to semi mess up or chances of it otherwise theres lack of flow
