 ### `Perf.getLastMeasurements()`
-Get the measurements array from the last start-stop session. The array contains objects, each of which looks like this:

-  "exclusive": {},
-  // '.0.0' is the React ID of the node

+Get the opaque data structure describing measurements from the last start-stop session. You can save it and pass it to the methods above to analyze past measurements.

+Don't rely on the exact format of the return value because it may change in minor releases. We will update the documentation if the return value format becomes a supported part of the public API.
