I got confused with your fourth and fifth paragraph. In the fourth one, you seem to be checking each operation after it's done by the child and adding another one if it's wrong. In the fifth paragraph, it seems you let the child finish the entire sheet and then add another sheet of operations (with n amount of operations based on the number of failures or another 64?) Could you clarify this further? Your method seems very interesting to me.
