After that I've read Derren Brown's books, "3510" by Luke Jermay, "Practical Mental Magic", etc.

Being a sometime mind reader, I know that Tomo was wondering why you did not know the method for Time for Change. It's one of the most common uses for one of the 13 steps.
Anyway, I also think you should steer clear of that manuscript. I am afraid that it sounds like yet another person who is reusing old methods (and not even with new presentations) and, I suspect, ripping off the creators of more recent things. It sounds suspiciously like a rebranded version of one of those "Do Derren Brown's tricks" e-books that were very popular a few years back. Some of the efects will be good, but if you want to learn them, your money should go to the originators (or on the classic books).
