- Use the page IDs to find the users that have edited those pages within the timeframe of the event. (Method should already exist)
- Then, with this list of users, find the New Editors and calculate the 7-day retention based on the operation that already exists and works inside GrantMetrics
7-day retention is an existing metric in Grant Metrics, but currently it works only when the user has defined a Participants list. For Event Metrics, we'd like to have this figure with or without Participants.
Definition of metric
- 7-day retention The % of New Editors (see definition below) who make at least one edit, in any Wikimedia project (in any namespace), between 7 days after the event and the time that the report is run.
- New Editors are a subset of "Participants" defined as a new accounts created, including users who registered up to 14 days before the event up until the end of the event period, on any wiki (for more on Participants and New Editors, see T208546).
