Frequently asked questions

Are these the official tables?

This uses a simplified age factor for a quick estimate. Official WMA/USATF tables are more granular but the percentages are close for most ages.

Do age-grading tables account for gender differences?

Yes, age-grading tables are calculated separately for men and women using gender-specific world-best standards at each age, so a grading percentage always compares you against athletes of your own gender and age group rather than a single combined standard.
