I first shared the idea in one of the issues of the Lunarium Newsletter and asked the readers to try the approach and tell me if it made sense for them. Several people responded that they found the method interesting and useful, so I went ahead and produced a whole book describing the approach and giving detailed examples.
The book is now available for free on the US and UK Amazon stores (from the 7th of May for 5 days), and for a minimal possible price in all the other stores. I am planning to keep it at that low price for a couple of weeks from now, as a promotion. Here are the links to the book on the different stores:
