  "source_difference": 910,
  "inverse_lower": [

  ],
  "inverse_difference": 910,
  "refined_lower": [
    4620,
    5530
  ]
}
```

## Finding

The lower Noah branch remains910 longer inLXX, both when grouped and when its shared lives are explicit.

## Reassessment

Use910+4030 to account for the complete MT/LXX inverse head separation.
