1. What is WMA Age Grading?

The WMA (World Masters Athletics) Age Grading system allows athletes to compare their performance against others of different ages and against world record standards. It provides a percentage score that indicates how your performance compares to the world record for your age group.

2. How Does the Calculator Work?

The calculator uses the WMA Age Grade formula:

Where:

• \( world\_record \) — World record time for the event (minutes)
• \( performance \) — Your performance time (minutes)
• \( age\_factor \) — Age adjustment factor from WMA tables

Explanation: The equation compares your performance to the world record standard, adjusted for your age group's expected performance level.

3. Importance of Age Grading

Details: Age grading allows fair comparison between athletes of different ages, helps track performance improvements relative to age, and provides motivation by showing how close you are to world-class standards for your age group.

4. Using the Calculator

Tips: Enter the world record time for your event, your performance time (both in minutes), and the age factor from official WMA tables. All values must be positive numbers.
