Strategic decision. Optimized time.
High-performance training is more than just a sequence of drills.
It is a complex process in which a coach must constantly make decisions. Technical and tactical developments are a constant part of a player’s career.
Being able to objectively assess this development – or simply ensure that the player is on the right track – means safeguarding the most precious asset in elite sport: time.
For the player, it is also a way of gaining maturity, self-awareness and, ultimately, confidence.

This allows for a qualitative assessment of training sessions. It’s also very useful—and something we sometimes forget—for evaluating training load. No coach in the world can say exactly how many forehands or backhands a player should hit during a session. It’s a smart way to train.

The ‘pro’ statistics provide more than 30 performance indicators. Combined with the coach’s match observations, this allows for even greater precision and clarity, and enables observations to be illustrated with factual data during the debrief. Hawk-Eye technology is also incorporated. This allows players to focus solely on the game. This saves valuable time.
