# C612 — Relate the989 interval to the weighted Actual bridge

## Question

Does the cumulative Abraham–Exodus interval provide one unit for both sides of12026?

## Inputs

```json
{
  "Abraham": 2435,
  "Exodus": 1446,
  "Creation_cumulative": 14004,
  "bridge": 12026,
  "Creation_regular": 4114
}
```

## Sources

```json

]
```

## Results

```json
{
  "unit": 989,
  "bridge_arms": [
    1978,
    7912
  ],
  "unit_coefficients": [
    2,
    8
  ],
  "expanded_unit": 1075,
  "expanded_arms": [
    2150,
    8600
  ]
}
```

## Finding

The989-year Abraham–Exodus interval supplies2 and8 units in the Actual Creation bridge:1978+7912=10×989. E sends the common unit to1075 and the arms to2150/8600, explaining the preserved1:4 partition. This is a derived duration interface.
