Alex, I am not very sure about layering. how do you know what you want on each layer? will you leave something important when doing the layering? from your posts, i don frequently see rapid read. is that not suitable for you or you prefer other methods? when super read and dip, is it necessary to go from fromt of the book to the end of the book or it is ok to skip into whatever page?
Thanks!
BTW, this thread is nice! y let it die?
Lets post whatever experiment you hav here
