hi GBD,
this is how i do it,

step1:
lets say for instance that i am activating the chapter on concepts of money, then with my pupose etablished i would super read and dip/ skitter for 6 min.
second step
i would establish a new purpose saying that , this time i will be creating a mind map and hence ask my inner mind to guide me to specific details and facts which are key words to capture the whole chapter on the mindmap, i would spend about 10 seconds on each page , this time it becomes easier to spot key points quickly as i'll have super read it before, then after the 10 seconds on the first page i would write all the key bits on the mind map, and continue the same with all the pages.

now i use the second step only when i am reading important information and its important that i have as much of understanding as possible, such as study material , if its for pleasure 1st step should be just fine.
