I thought the best idea in learning was to review each paragraph twice and to go on. This was the compromise that I made for myself in the great Litvak yeshivas Shar Yashuv and the Mir when there was this tension between intense deep learning and the path of Rav Nahman of just saying the words and going on.
Each of these two ways just did not work for me. If I just said the words and went on, I understood nothing. And if I sat on the same page doing lots of review, I also had no idea of what was going on.
So I found this sort of compromise to be the most sensible thing. With review twice, I more or less got the idea, but I did not linger on the same page in such a way that I made no progress.
Anyway that is how I learned in Shar Yashuv and the Mir. After that I did the "Say the words and go on" approach. And that is how I learned most of the time. [ After that I needed to find some way of making a living, I majored in Physics at the Polytechnic Institute of NYU. To do that I needed a lot of review.
[I knew one fellow in Breslov who in fact took this advice of Rav Nahman very much literally, He used to finish Shas every month. (The entire Talmud.) He pointed out to me that this is not hard if you just come in in the morning and start going through page after page. Thus by the end of the day, you have gone through about 100 pages.] But that is only for the fast bekiut sessions. Nowadays I think one should emphasize the Litvak approach of deep iyun [Deep learning] because I think that is the only way to get to the light of Torah; and in math and Physics also I think deep learning with tons of review on the same chapter is the best approach. But is agree that fast learning is good in the afternoon [as was done at the Mir.]
