How do you know if you are adjusting correctly and quickly enough when playing ? By the results you may reply. But it is possible to win playing badly and to lose playing well, and it is important to know that you can only play as well as you are allowed to. An effective coach, who observes constructively, can supply the answer. If you want to give consistently good performances, you will need frequent assessments to confirm your correct actions and help you adjust more effectively in the future and thereby become a regular playmaker.
