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 in Stevenson, Carson, or Cascade Locks.

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".

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?
