@tilt the problem you showed me was bothering me, so I took some time to look into it. I believe the reason `scope.progressInPercent` was `undefined` comes down to Angular's scope hierarchy.

Compare:
```js
element.scope().$id; // => '015'
element.scope().progressInPercent; // => undefined

cell.scope().$id;  // => '017'
cell.scope().progressInPercent; // => 20
cell.scope().$parent.progressInPercent; // => 20
cell.scope().$parent.$parent.progressInPercent; // => undefined
```

In the end, it was probably a good thing you didn't test this – as it's effectively like testing a private method.
