mateo,
PRing books is just like regular reading them but faster. Now, if you were to regularly read a martha stewart home decour book, would you develop that professional taste for home decorations after reading the book? I think not. You might understand a little more than you did about home decorating, but you wouldn't have magical results. It is the same with PRing. PRing is not magical, it simply reduces your reading time by a third.
