Prize money distribution

Key
These tables present the number of singles (S) and doubles (D) titles won by each player and each nation during the season. The players/nations are sorted by:
 * 1) Total number of titles (a doubles title won by two players representing the same nation counts as only one win for the nation)
 * 2) A singles > doubles hierarchy
 * 3) Alphabetical order (by family names for players).

To avoid confusion and double counting, these tables should be updated only after all events of the week are completed.
