# C1184 — Recover amplitudes from local named observations

## Question

Which five source differences identify the unrestricted model?

## Inputs

```json
{}
```

## Sources

```json
[
  "C1182"
]
```

## Results

```json
{
  "recovery": {
    "path": "model/whole_genealogy_local_recovery.json",
    "sha256": "02ec326eb620855f03d145bedfec53dc2653efb6ee52b3679550b22c9c3d893b",

  "observations": {
    "Adam:b": 100,
    "Lamech:L": -24,
    "Arphaxad:L": 27,
    "Eber:L": 40,
    "Nahor:L": 60
  }
}
```

## Finding

Adam’s begetting difference and four named lifespan differences recover the five amplitudes directly. The four-parameter version predicts a relation among these five already-known observations.

## Reassessment

Determine exactly what the two chronology head differences conceal.

## Checks
