How this list is made

  1. Every project Hysen Labs tracks is snapshotted once a day. A project's gain is its Star count at the end of the window minus the count at the start.
  2. Archived, mirrored and unlisted repositories are left out, and so is any project missing a snapshot near either end of the window; nothing is estimated.
  3. The arrow compares each place with the same window ending a week earlier.
