5k percentiles

Have you claimed your handicap score and do know where you sit on the National Ladder - overall, within your gender, within your age group, within your postcode, within your postcode and gender, within your postcode and gender and age group??!!
We're sure you will agree that it's fairly straight forward to get stuck into stats with the enhancements that have been made to the rankings site over the past couple of years. We're also pleased to see that they are being used in the wider media.
Last year The Guardian Running Blog used the data from the rankings site to show runners the percentile their 5k time put them in.
The full data is as follows:
Men
Of 376,427 total performances
>1% - 17:19 or under
>5% - 17:20 - 18:52
>10% - 18:53 - 19:50
>20% - 19:51 - 21:13
>30% - 21:14 - 22:21
>40% - 22:22 - 23:24
>50% - 23:25 - 24:26
>60% - 24:27 - 25:34
>70% - 25:35 - 26:54
>80% - 26:55 - 28:41
>90% - 28:42 - 31:40
So, for example, if you are male and have run quicker than 17:19, your
performance is in the top 1% of all 5K performances (up to June) in 2013 from UKA licenced races.
Or – see below -– if you are female and have run quicker than 29:30, your performance is in the top half of all 5k performances from UKA licensed races.
Women

>30% - 25:48 - 27:10
