Begin with the effect the ball needs to have on the opponent. To move an opponent back, for instance, the player may need more height and depth rather than a faster swing. Consider speed, spin, trajectory, direction and depth as parts of the same ball.
The intended effect on the opponent
Begin with the opponent’s situation. Do you need time to recover, a lower contact for the opponent, greater depth or a ball that moves them away from their preferred position? This makes the desired ball specific. “Hit better” offers no comparable information.
Combining ball qualities
More speed can reduce available margin if trajectory and spin do not fit. More height can help a defensive task but may allow an opponent time in another situation. The aim is a purposeful combination. Observe the path of the racket, its face orientation and the incoming ball together to explain the resulting shot.
Testing control against variation
A player may control a target from a predictable feed yet lose it when the ball changes depth. Include movement and different incoming trajectories. Assess whether the intended effect remains recognisable, rather than insisting on an identical swing for every ball.
Final reflection
Measure control by whether the player can produce the required flight and placement against changes in the incoming ball.
