Okay, so this is just a suggestion, I think it's a fun cool stat that the site could use, but I'm not the guy responsible for that, so only if others also like this new 'stat' I came up with, then maybe.

Anyways, it's Harambey here guys, and I came up with a new ranking method: Track Rating!
So basically what this ranking does, is that it takes the stats from the PRSR, AF and Standard rankings, combines them and then gives your PR for a track a percentile rating, to show you how good your time currently is! The higher that percentile rating, the better your PR is at that moment. And the lower it is, the weaker your record is, thus you should likely try to improve it, as it's easier to improve it than other tracks, and because it's one of your worse PR's.

So how does it work? Well, first of all you take a look at your AF ranking for one specific track. You take the number of players that you BEAT and divide it by the total number of times. For example, if you're 400th out of 500 players, you beat 100 players, thus your AF percentile becomes 100/500 -> 0.200.
Then, you take the percentile from the PRSR stat. Nothing to change about that, just take that percentile as it is.
Lastly, you look at your standard rank. There are 34 ranks, so you divide your 'standard rank' out of 34. Newbie is rank 1, Beginner D number 2, and so on with God being 34. Then you divide that number out of 34 and get your final percentage.
Finally, you add up these three percentages and divide it by 3. Then, you got your Track Rating!  
Here's a quick example:
Random Player: Toad Circuit = ( 100/500 + 0.9000 + 17/34 ) = 0.2 + 0.9 + 0.5 = 1.6 / 3 = 0.533...

Remember: The HIGHER your percentile, the BETTER your record is, and the LOWER it is, the WORSE your time for that track is.

Also, as it can take quite a lot of time   to calculate the TR (Track Rating) for each track yourself, if others like to have this stat then maybe it would be nice to include it on the site???  

I think you could probably like this stat, because I see players very regularly saying that they only play tracks when it's worse than the others, or something like that. It would be very helpful to see on the site what your better and worse times are, at least, I'd like to see it!

And good luck improving your times no matter if it's good or bad!

Can't you just organize your times by standard ranking, look at your worst ones (say, RRM or RAF) and shave off AF by working to improve those instead? Seems like it'd have the same effect.
