OK: nearly impossible to understand because the English is not written by an English speaker. Overly complicated, There are much simpler systems Some of the systems don't even work (i.e;:reversing the rail system).
I doubt Ceulemens even read the book much less wrote it. This is borne out by Coulemens saying he never learned any systems until after he won his third world title. BTW, in 1996, I was standing next to Caudrone who is Ceulemans' protege when someone asked him where the "Mr. 100" book could be found. Caudrone looked askance and said, "I have no idea.". Obviously he didn't have one.
Same goes for Hoppe's book: the diagrams for the corner five system in that one make no sense. Also the chapter heading is THE DIAMOND SYSTEM. As if there were only one. Most all systems are diamond systems.
