Responding to a single request for oversight may require multiple suppressions, revision deletion in place of suppression, or no suppression at all. For the purpose of these statistics, one action equals one log entry (and every log entry may involve more than one diff).
Revisions hidden using RevisionDelete by administrators are not included.
Suppressions performed by stewards, developers, or Wikimedia Foundation staff who are not also appointed Wikimedia Commons oversighters are not included in these statistics.
An empty cell means the user did not have the oversight permission at any time in the given month. A cell containing "0" means that the user had the oversight permission at some point in that month, but made no logged actions.
