What is PSI?

Welcome to the revolutionary world of the Performance Stats Index (PSI), meticulously crafted by a professional tennis coach with the assistance of professional coaches and tour players.

How PSI Works

PSI employs a sophisticated algorithm that evaluates player performance based on several key metrics, providing a comprehensive overview of their strengths and weaknesses. The grading system takes into account:

  • Good Shot to Bad Shot Ratios

    Measures the quality of shots played by a player.

  • Ratio Differences

    Analyzes the variance in performance ratios, highlighting consistency or fluctuations.

  • Games Played

    Factors in the overall impact of games played during a match or tournament.

PSI Ratings and Grades

PSI provides users with a simple and accurate measure of a player's performance in terms of four areas

  • Serve

    Evaluates a player's service performance.

  • Groundstroke and Auxiliary

    Gauges a player's performance in groundstrokes and other key facets of the game.

  • Overall

    Final comprehensive measurement of a player's performance.

  • Return of Serve

    Assesses a player's effectiveness in returning serves.

For each area, performance is graded in terms of

  • Excellent Performance
  • Above Average Performance
  • Solid Performance
  • Below Average Performance
  • Poor Performance

Near Real-Time Performance Evaluation

Unlike traditional rankings and ratings, which reflect accumulated past performances, PSI focuses on the present moment. It recognizes that player performance can vary from tournament to tournament, match to match, and even within a set. PSI simplifies this complexity, offering you valuable insights into a player's current form after each set.
