I also bought it, I really like the schemes of this author. To overcome the difficulties of reading the only one is to color a disposable copy of the scheme with pastels. Still worth it!

Superb! But the grid, on 4 A4 pages, in black & white, is not easy to read and requires good eyes or a magnifying glass! Suddenly, no other choice but to enlarge but Print of poor quality to pass in A3 format. Suddenly, the grid is expensive given its difficulty of reading.
