I have a similar issue with apparently strange age-graded results, but editing the results as above does not correct the calculation.
Dean Drew 3:56:07 53.22% 9:00 min/mile 45-49
Adrian Grimshaw 3:56:07 55.69% 9:00 min/mile 35-39
Here, the 2 “athletes” ran the same time but the 2nd, being younger, should have a lower age-graded result (the actual difference is 9 years, but you can see from the categories the approximate difference).
Any ideas? This could be an issue in the supplied % data, but I don’t have access to SQL on my current site.
Thanks in advance for any help.
