2014 ATP Surface Speed Ratings

My surface-speed metric uses ace rate--adjusted for the servers and returners in each match--to rate each tournament by surface speed. Thus, the number indirectly accounts for everything that influenced play: temperature, humidity, wind, balls, and of course the physical surface.

Ratings greater than 1 are faster than average. For example, a rating of 1.25 indicates that the players hit 25% more aces than they would have on a tour-average surface.
