Hi.
Perhaps you could liken it to a carpenter who does not use a saw, a hammer or nails.
Or maybe you could liken it to a mechanic who does not use a wrench or diagnostic computer for analysis.
My point is preview, superread & dip, activation are processes used to help you peel another layer of the book. Layers it is all about layers & when you get rid of the layers you are stopping yourself from getting anything from the book.
You said your purpose is to become a better writer. That does not sound like a purpose because it lacks the so that i can do component of a purpose. You notice in the photoreading book Paul Scheele mentions that a purpose includes how you are going to apply the information or use the information.
The way you describe it it sounds like you just want to photoread the book and not have to make any effort to get anything from the book.
So you do not have a purpose and purpose is everything in photoreading and you do not want to use any of the activation techniques so i say no that is not going to work for you.
