If you don't have a purpose why activate? It can be the same purpose for each session until you feel that you've been filled or got everything from the book that you need right now.
when dealing with technical stuff it is easy to get pulled into analytical reading too soon. That might be why you sometimes dip 2 pages. The trick is to pull away just before you know everything and remember if you need more you'll wind up getting a mind probing question and think of the answer or superread and dip that section again. It's still faster to superread and dip a page 3 times than to have one long dip that last 2 pages. Remeber clarity comes in layers.
