Yep good post
By the way, CX changed our manuals 5 years ago to remove the requirement to report leaving/maintaining a Level whilst Radar identified. I haven't made such a call in Oz since then and haven't been told off!! In my hours and hours of listening in whilst droning over Oz I hardly ever hear any Oz operators do so either. It is the 21st century after all!!
Progress!!
This is all mute anyway, give it 10 years and it will all be CPDLC!!
