One family, one season, the numbers.

The guides say what to do. These say what happened when a family did it: the match, the car ride, the lesson, and what the record showed three matches later.

• What a coach opens before a lesson

  Two minutes in the coach console before a Monday lesson, the week it showed, what the coach wrote, and what the next tournament proved. Real numbers from one family.

• What one tracked match showed, and what three later ones proved

  One Level 4 match tracked from the fence, what the record showed that memory could not, the one habit a coach changed, and what three later matches proved.
