## Results

```json
{
  "MT": {
    "upper_gain": 990,
    "split_loss": 4320,
    "predicted_change": -3330,
    "observed_change": -3330
  },
  "LXX": {
    "upper_gain": 7020,
    "split_loss": 4320,
    "predicted_change": 2700,
    "observed_change": 2700
  },
  "SP": {
    "upper_gain": 0,
    "split_loss": 4320,
    "predicted_change": -4320,
    "observed_change": -4320
  }
}
```

## Finding

The common law gives−3330, +2700 and−4320 forMT, LXX andSP, exactly the observed three responses.

## Reassessment

Trace the large LXX upper gain to its source rows and decimal register.

## Checks
