Flow patterns (42-month cumulative)
Inbound (numbers acquired)
| Direct transfer from another RespOrg | 133,476.0 |
| Harvested from disconnect pool | 783.0 |
| First assigned from spare pool | 52,338.0 |
| Reactivated own disconnects | 3.0 |
Outbound (numbers lost)
| Direct transfer to another RespOrg | 45,872.0 |
| Standard disconnect aging process (3+ months in DISC) | 0 |
| Abbreviated disconnect period (1–2 months in DISC) | 307 |
| Released directly to spare pool | 18,800.0 |
Of the 307 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.
