Hi Mikel,
This is not a mistake! When the book was laid out it was determined that only 10 exercises can fit on each of the summary pages. In reality, there are many more exercises but I believe these are the most important for now. You are definitely encouraged to include any exercises not included in the summary.
Throughout the years, I have thought of maybe releasing another workbook of additional exercises which I now incorporate in my one on one lessons as needed. Who knows maybe I will…
