     Stopped --> [*]

-Please note: the 'Stopped' state in the `handleRotationImpulse`'s state machine is a direct consequence of either `rower.js` indicating the flywheel is in a freespin or reaching the end of an interval without any subsequent interval being present in the workout. The later is tested in the function `handleIntervalEnd()`, which determines this. Although this distinction could be handled by the state machine as part of `handleRotationImpulse`, we felt it would make the state machine less readable as it would add another three new states.
+Please note: `handleRotationImpulse` implements all these state transitions, where the state transitions for the end of an interval and the end of a session are handled individually as the metrics updates differ slightly.
