LOL. Here we go with the slow court conspiracy theorists.
No numbers back up what you are claiming.
Plenty of statements from tournament directors discussing their experimenting with court and ball changes to slow down the game, statements from various players on both tours, and of course personal observations and interactions with courts.
The numbers don't exist, not our faults as none of us have the resources to quantify these things. That's up to the ATP/ITF, and they obviously do a poor job at it.
