Flow patterns (42-month cumulative)
Inbound (numbers acquired)
| Direct transfer from another RespOrg | 26,790.0 |
| Harvested from disconnect pool | 22,557.0 |
| First assigned from spare pool | 777.0 |
| Reactivated own disconnects | 483.0 |
Outbound (numbers lost)
| Direct transfer to another RespOrg | 1,260.0 |
| Standard disconnect aging process (3+ months in DISC) | 0 |
| Abbreviated disconnect period (1–2 months in DISC) | 7,957 |
| Released directly to spare pool | 1,172.0 |
Of the 7,957 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.
