Rav Freifeld the founder of Shar Yashuv used to emphasize learning every chapter ten times. And when we were doing Ketuboth and Hulin this created for me a certain degree of tension.--For I wanted to "make progress." I think after a few years have passed, I can now see his point. And thus I would even like to share his idea with the world, that one never needs to give up if he or she encounters something hard to understand in his studies. Even after doing one chapter, one still does not understand. What I suggest is doing that chapter 10 times and then going on. [Or going back to the previous chapters if one is inclined at that point to do review.]
I had a sort of conflict between bekiut and iyun [fast learning and in depth learning]. For that reason I decided on a system of repeat every paragraph But when it comes to some subjects like physics I find the idea of review ten times of each chapter to be the best.]
