The “10,000-hour rule” famously suggests that mastery is built through immense dedication. The core principle is transformative: you become what you practice. Spending thousands of hours on a skill fundamentally embeds expertise into your being, making consistent effort the engine of high achievement.

However, time alone isn’t the whole story. As detailed in the book Peak, the key is “deliberate practice”—a focus on quality, not just quantity. This involves purposeful, goal-oriented effort with constant feedback. Inspired by this, I incorporated the concept into my app. It moves beyond a simple hour-counter, guiding users to set specific, challenging goals for each session and track their progress with targeted feedback loops. It transforms the 10,000-hour journey from a marathon of repetition into a strategic climb toward true expertise, ensuring every minute of practice is a deliberate step forward.

With this being said, DPTennis focuses on the deliberate improvement of rising tennis stars. With calculated feedback and detailed stats providing the best experience of a post match review, players can now effectively determine their priorities when it comes to their tennis.
