Having looked at the 10 year cycles I'm passing on it.
My 'cycles' are so erratic and have little pattern to them that it's frustrating me to see any correlation with the exercise and my own personal life.
It doesn't follow that every 10 years some major event takes place in a person's life, for some it may be more frequent for others less so and I'm struggling to establish the pattern.
I'm moving on to the next exercise regarding the most frequently occurring year cards.
