Performance data is the key building block to mental development
“Tennis is a mental game.
Everyone is fit. Everyone hits great forehands and backhands.”
NOVAK DJOKOVIC
Why focus on performance data and mindset in tennis?
At EGW, we have two key goals.
First, to minimize the pressure of match play. Stress comes from being judged on results—something beyond direct control. Performance measures, however, are fully controllable and independent of level or outcome. You can perform excellently without winning the match, and win without performing excellent.
Second, we help our players to develop a growth mindset. Our performance metrics focus on the most critical abilities for becoming a successful competitive player. By tracking the most relevant measures.
So, why do we neglect the most crucial skill for competitive tennis?
Short answer: Because we don't measure it.
The famous quote: “What gets measured gets done.” from Peter Drucker apply also in sports. In tennis, technique is visually tracked from day one, physical ability is measured a little later but remains straightforward to quantify. That’s why competitive juniors consistently develop technique and physique with no or small differences.
Yet, everyone agrees: The true divider is mentality.
Emotional strength, has been hard to measure. Therefore it vary widely amongst competitive juniors with equally good technique and physique.
Here is how we measure it.
# 1: Focus measurements
The athletes ability to stay in the present and not let the past influence the focus on the next point difference players. Naturally this is a metric you need to measure and progress on in order to reach your full potential.
# 2: Momentum measurements
One key characteristic of mentally strong athletes is that when they do lose focus they bounce back. relatively fast. We measure this metric so you can acknowledge it and start to progress on this crucial ability.
You vs You
The only tennis player you should compare yourself to is the one you used to be. This is important. It takes unnecessary pressure of and is the key to a growth mindset.

Novak Djokovic believes that mental skills can – and should – be trained as systematically as technique and physical ability. Our service EGW makes it possible to measure and develop mental performance – because what gets measured improves faster. Get the edge.
