The Age-Grade Calculator’s underlying age-grade tables can be applied to five-year age groups or individual ages from 8 to 100. The only official use of the Age-Graded Tables by WMA is in scoring multi-event competitions. But, the Age-Graded Tables have been incorporated into track meet management software by Hy-Tek and others. They are used to determine age-graded winners in many other competitions, especially road runs.
