Flow patterns (42-month cumulative)
Inbound (numbers acquired)
| Direct transfer from another RespOrg | 3,201.0 |
| Harvested from disconnect pool | 72.0 |
| First assigned from spare pool | 2,388.0 |
| Reactivated own disconnects | 0.0 |
Outbound (numbers lost)
| Direct transfer to another RespOrg | 38,061.0 |
| Standard disconnect aging process (3+ months in DISC) | 7 |
| Abbreviated disconnect period (1–2 months in DISC) | 40 |
| Released directly to spare pool | 2,490.0 |
Of the 47 disconnect episodes this RespOrg has sent through aging, 85% 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.
