Below are the updated Riles Clubhouse ratings after the 2015 French Open. Lots of change in the ratings with Wawrinka moving up and Nadal moving down. The RilesClubhouse methodology and advantages are described here (http://wp.me/P4ETDC-W).
The Riles Clubhouse rating system does differ from the ATP World Tour rankings. Namely, the Riles Clubhouse rating system just looks at who a player won & loss to instead of how far they advanced in a given tournament. Also, the Riles Clubhouse system does not penalize for missing tournaments. Below is a comparison of the Riles Clubhouse rating system and the ATP rankings. The most under-ranked players include Andrey Kuznetsov, Simone Bolelli, and Nick Kyrgios. The most over-ranked players include Pablo Cuevas, Ivo Karlovics, & Fabio Fognini.
