# C1495 — Lift the local action to the joined path

## Question

How does the Key change the LXX-head-to-exile total when the upper edge stays fixed?

## Sources

```json
[]

## Results

```json
{
  "before": [
    13136,
    5436,
    606
  ],
  "after": [
    13136,
    5436,
    536
  ],
  "legs_before": [
    7700,
    4830
  ],
  "legs_after": [
    7700,
    4900
  ],
  "totals": [
    12530,
    12600
  ]
}
```

## Finding

A local action on the final radius changes 12530 to 12600 while retaining the 7700 edge.

## Reassessment

Check that a whole-span expansion would be a different operation.

## Checks
