Details
I am an avid tennis player and web designer. I graduated from the University of Utah in Electrical Engineering. While in school I started working on this site and never looked back. I now code for a living, and work on this site every chance I get. Let me know if you have any ideas or suggestions for the site.

Looking for a tennis partner to play on weekends, or nights. I live in Downtown Portland.

A great new way to find a tennis partner is to post a comment to your location. All the players at your location will be notified when you do. Just go to your profile page, and on your "Comment Feed", write a comment and and click "Submit to.. -> Location Players -> YOUR CITY".

You can now upload pictures, videos, or files to your profile page. You can even embed YouTube or Vimeo videos. Just look for the "Media" tab on your profile page. This is a great way to showcase your skills, get feedback from other players, or just share your favorite tennis pictures and videos.

Heh Trevor
How do I remove a player from having admin right since he's no longer in the ladder?

Hi Trevor,

Can you pls show me how to calculate the double ranking points? It's kind of different of single's, isn't it?


Ra(new) = Ra(old) + K * ( W – Ea )
Rb(new) = Rb(old) + K * ( W – Eb )
Ea = 1/(1 + 10 ^ ((Rb-Ra) / 400) )
Eb = 1/(1 + 10 ^ ((Ra-Rb) / 400) )

hi Trevor,

Just curious. I don't quite understand how the ranking system is using ELO Ranking method to calculate the points. The forumla is kind of like below from website 'http://elorankings.com/'.

I set K as 800.
Ra(new) = Ra(old) + K * ( W – Ea )
Rb(new) = Rb(old) + K * ( W – Eb )
Ea = 1/(1 + 10 ^ ((Rb-Ra) / 400) )
Eb = 1/(1 + 10 ^ ((Ra-Rb) / 400) )

Got A win B as 6:3. A original point is 1693, B original is 1608. Base on the website, it change to A is 1705, and B is 1592. However, I just the forumla above, the EA is 0.619941, EB is 0.380059, so A change to 1997 instead of 1705, B change to 1303 instead of 1592. Any ideas?
