Yes, it does work well and is defintiely worth your time....it may even become your template for learning all future material.
If you have finished the PR Book, then give it a try. Pick a topic that gets you jazzed, find a book on that subject, and follow the program. Before hand, make a mental determination of how long (in hours)it would take you to "read" the book using your old method of reading/learning. At the conclusion of the 5 day test, note that you have only spent 2.5 hours on the book...how do you feel? Are you comfortable with your level of learning/comprehension. Then note that this is only your first time PR'ing and it took you years to learn to read the other way. I bet you'll feel pretty encouraged.
Good luck and have fun.
