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 Call8 plus its siblings); these lines only compare how fast each is changing. When Call8 sits above Kall8 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.

Flow patterns (42-month cumulative)

Inbound (numbers acquired)

Direct transfer from another RespOrg	1,943,964.0
Harvested from disconnect pool	4,575.0
First assigned from spare pool	423,096.0
Reactivated own disconnects	21.0

Outbound (numbers lost)

Standard disconnect aging process (3+ months in DISC)	2
Abbreviated disconnect period (1–2 months in DISC)	27,058
Released directly to spare pool	414,076.0

Of the 27,060 disconnect episodes this RespOrg has sent through aging, 100% were abbreviated (1–2 snapshots in DISC status). That's a strong early-disconnector signal, this RespOrg routinely releases numbers before the full 3–4 month aging window. Worth checking daily for vanity drops.
