Previously the tomography wasn't using ember `get` so proxy updates (specifically here whilst receiving a blocking update) wasn't working. This adds `get` here until we update to newer `get`less ember and also refactors slightly removing `n` and using `distance.length` instead Skipped tests are adding here to nag us to come back here at some point.
