There should be no reason you cannot SuperRead & Dip through the text, building conscious comprehension very, very quickly in layers, from whole-to-parts. Structure first, and layer upon layer of more and more detail with each 30-minute activation pass.
As a rule of thumb, the higher the level of comprehension you want, the more 30-minute activation passes you will have. You'll be building "better" comprehension that your inner mind will be able to reconstruct later at a conscious level much more efficiently. And, you will end up spending a 1/3rd to 1/5th the amount of time to achieve the same comprehension level than you would have to spend with regular slow reading, one word at a time at one speed left-to-right.
