This Resp Org vs its group

Each line shows the percentage of its own starting level retained, so you compare the rate of change, not the absolute size. The group is larger in raw numbers (it contains Amazon.com plus its siblings); these lines only compare how fast each is changing. When Amazon.com sits above Amazon it has shrunk less than its group overall (more resilient); below means it shrank more. A member holding steady while its group falls often means numbers are moving to siblings within the group, not being lost.
