Percentiles on Leaderboards

With 1000s now on the mountain at any time, the chances of being near the top of a leaderboard are very slim.  Moreover, the meaning of your place when not on the leaderboard is dependent on the number of people riding at that time.  

To get more use out of it, how about percentiles are also calculated and given e.g percentile 21, you are faster than 79% of riders.
