While I agree that the author's method likely helps comprehension and retention, I disagree with his premise that it is necessary for these, or even particularly time-efficient. His key factor seems to be "Learning comes from repetition"; though important to he learning process, repetition is neither the sole, nor even the primary factor. When it comes to retention of concepts, rather than raw data, comprehension and connecting to other knowledge is crucial.

In the author's method, these are reinforced with marginal notes (for comprehension) and a post-reading writeup (to connect concepts). I suspect this to be significantly inferior to more in-depth note-taking, as a significant amount of information may be lost in the time between reading chapter one and finishing the book, whereas complete notes should allow for immediate relation and processing. A high quality book will be organized to assist the reader in relating concepts, and waiting until book completion to prioritize this defeats the purpose of reading a book rather than a collection of disparate articles.

Still, the author is absolutely correct in that active reading is a worthwhile habit, and you should try to find an optimal method for your learning tendencies; While for me focusing on repetition and post-read review is brutally inefficient, everyone learns differently, so it may be perfect for you.

The author mentions writing down a summary after every chapter in the book itself. The final notes are prepared from each chapter's annotations and handwritten summaries. If anyone is interested in reading to retain more, try How to Read a Book [1] by Charles Van Doren and Mortimer J. Adler. Reviews and summaries of the boook [2, 3].
