That sounds good because the text has things that jump out at me on every page (highlighted vocab, colored headings with large font, etc.) which makes activating a long process for me. Also, for me, I seem to prefer postviewing over previewing. I only try to preview the material for a few minutes because like I said above, there is so much info that I could pull out interesting things everywhere, bogging me down before I even PR. So, by PRing the same material often and by not dipping too much each time should make things a bit easier? It sounds good and i've basically been doing that with the exception of activating for a long time each PR session of the material.
