# C1588 — Locate the SP source displacement

## Question

Which local lifespan differences produce the120-year SP cumulative Flood displacement?

## Sources

```json
[

## Results

  "names": [
    "Arphaxad",
    "2nd Cainan",

    -60
  ],
  "sum": -120,
  "Eber": -60,
  "Terah": -60
}
```

## Finding

SP Eber and official Terah each subtract60; all other shared post-Flood rounded lives agree with MT. Their120 reduction is inherited from source rows.

## Reassessment

Determine how far the MT–LXX910 and MT–SP120 translations propagate before the upper source lives change them.
