Games per Set (GPS)

The table below displays the average number of games played in a set at each individual tournament (1997-2007).

Court speeds
The ITF do categorize surfaces, category 1 (slow), category 2 (medium/medium fast) and category 3 (fast), though the time of day, weather, temperature and type of ball being used all have a bearing on how fast the courts play.
A useful way to gauge court speeds is how many games are played in the average set (Based on the theory that the quicker the surface then the harder it is to break serve, thus resulting in more games per set).

The figure has been reached by dividing the total number of games played by the total number of sets played, dating back to 1997.
