  "MT": {
    "source": 7620,
    "core": 762,
    "zeros": 1,
    "inverse": 2670
  },
  "LXX": {

    "inverse": 6700
  },
  "source_difference": -20,
  "inverse_difference": 4030
}
```

## Finding

7620 reverses to2670 while7600 reverses to6700. The selected row difference crosses the significant-core/trailing-zero register, producing+4030.

## Reassessment
