Age Grading - how it works
Age grading uses tables of "age factors" and "age standards" to put all runners, regardless of age and sex on a level playing field. In particular, they allow runners' performances, no matter what their age, to be corrected to what they would have been achieving in their prime years, and permit valid comparisons to be made between people of different ages. The tables also provide each individual with a percentage value for an event, allowing them to judge their performance against the standard for their age both now, and keep track of their progress over time. The current tables (2006) were compiled by the World Association of Veteran Athletes (WAVA), the world governing body for masters (veterans) track and field, long distance running and race walking. The process involved analysis of masses of actual performance data. Curves were plotted, one for each event, "fitting" all known performances, including, for example, Lynford Cristie's 9.87sec 100m, at age 33, and Priscilla Welsh's 2.26.31 marathon at age 42.
Example results
A man of 45 runs 100m in 11.59. The 100m factor for men of 45 is .9220. Now, multiply 11.59 by .9220, which gives 10.69 as his age-graded time. The 100m world record is 9.79. The world record 9.79 * 100 / the age grade timeof 10.69 gives you 91.62% as his age-graded performance.

Revision of Age Grading Tables - 2010
WMA has decided to accelerate its periodic modification process of the Age Grading Tables to remove various deficiencies that have developed over several years as a result of new statistical information. Vice President Stadia, Rex Harvey, after extensive research with experts on the subject and review during the recent Stadia Committee meeting, has announced to solicit assistance to assure timely completion of the modification for final review and approval by Council during its next regular council meeting at the Lahti championships in July 2009, and implementation as of the next possible date, May 1, 2010.
