Fast Reading Guide Book by Gordon Wainright

[Rezafo]

There’s a book to help you develop your reading speed called “How to read faster and recall more” by Gordon Wainwright 3rd edition.
My question is that is this book addressing native speakers of English language or no both native and non-native speakers?

Do you think should any difference be made writing this type of guide books when addressing native and non-native speakers?

I have another question regarding one of the strategies of reading fast, but I will raise it in a separate post.

Not really- it's dealing with a skill that both native and non-native speakers use. It may be aimed more at native speakers, but if the techniques are useful, they could be useful to anyone.
