I'm sure this would be clarified in the book, but it seems their tips are best for gaining proficiency in quickly and accurately recollecting things you have already seen before, and not necessarily for learning something for the first time. I've certainty studied subjects where it takes ~20 minutes to recollect last lessons ideas into my head before I can proceed to new things, and for those types of subjects I think the 3 hour study block would be superior to the 30 minute blocks.
