In preparation for a new release of my app I decided to delete test data from the leaderboards. This is done by going to App Store Connect > My Apps > (the app) > Services > Leaderboards > Delete Test Data. The longest running leaderboard (running for over 2 years) previously had about 27,330 entries. It now has about 26,720, so about 610 entries have been deleted. I would have thought, there would not have been more than 10 test scores on the leaderboard, so far more have been deleted than I would have expected. Can anyone suggest an explanation for this? In particular, I am wondering if the delete also "cleans up" any scores for players who are no longer known to Game Center? Or perhaps it also deletes scores that are over a certain age, maybe 2 years? At no time has there been a public test link, nor have I ever given out any promotional codes.
