World Number Ones

Until November 2011 the official ranking system was the CGS Grade. In November 2011 this was replaced by the Dynamic Grade.

In 1995 the smoothing algorithm used to produce the grade from the index was altered to make it less volatile and so only number ones since 1995 are listed.

The Dynamic Grade list shows what would have happened if the DG system had been in place since 1991.

Changes are only considered at the end of an event.
