I ran an indoor mile this evening. on one age-graded table, my time came to a score of 75.23. On another website, the same time came to a 75.35. On a third website, it came to 75.37% Why is there no consistency? Are some of the sites possibly not updated every year? Shouldn't all the sites be operating from the same chart?
And according to the USATF's own tables, it came to a 75.19%.
So four different sites, and four different percentages?
You could just use the time for comparison, this is pretty common in running.
Had a similar thing happen--different scores from different web sites, but the MAUSATF Grand Prix series uses this one, so I go by it too:

Here's what they have under "scoring":
"The 2006 Masters Age-Graded Tables, updated in 2010, developed by World Masters Athletics (WMA) will be used to score results in each race. Each finisher's time will be divided into the standard for his/her age and gender; this calculation produces a performance percentage used in the Age-Graded competition."
Thanks. This must be what the usatf uses . . .
