To assess consistency, look at the quality of the ball the player repeats. In a cooperative rally, a short ball may keep the exchange going. In competition, the same ball can leave the opponent comfortable enough to take control.
The quality of the intended ball
Depth, net clearance, direction, spin and speed interact. The aim is not to maximise them all. A neutral rally ball may need enough height and depth to hold position; an attacking ball may justify a different risk. Establish the intended effect before counting consecutive shots.
Choosing an appropriate margin
Margin is part of an ambitious game. A player can aim at a demanding area while keeping sufficient space from the lines. Spin and trajectory can help shape that margin, but they do not compensate for every timing or spacing problem. If the ball repeatedly lands short, observe whether late movement is limiting the player’s contact.
Testing consistency under pressure
A cooperative rally is a starting point. Introduce changing depth, movement and a score so the player must maintain the same useful quality when conditions vary. If the standard disappears, simplify the task enough to identify whether the limitation is technical, tactical or attentional.
Final reflection
Measure consistency through the quality the player can repeat against an opponent. Consider what each repeated ball allows the opponent to do.
