Right-of-Way when "Running"

Right-of-way (RoW) rules while sailing on the beat, i.e. close-hauled on the way to the windward mark, are usually well understood: the Port/Starboard (rule 10) or Leeward/Windward (rule 11) situations are common after the start when the fleet is still packed, and most people usually get the points about who has RoW then.
However, things become more cloudy, maybe less obvious when we turn our backs to the wind and sail on the run, i.e. downwind almost on the lee of the wind.
Here is an illustration to be used as a tell-tale or a keepsake.
Feel free to discuss the points in the comments section. Cheers!

Sorry little mistake in the diagram: in case D, Yellow would retain RoW after gybing to port.
With both boats on port tack, the situation would revert to B, Yellow being the leeward boat so RoW, and Blue still having to keep clear.
The only limitation on Yellow remains rule 16 “Changing course”, as in all the others cases.
NB: a gybe (or jibe) is a change of tack when sailing downwind, and is different from “tacking”, a change of tack when sailing upwind resulting in the boat passing head-to-wind as she tacks. Loss of RoW when changing tacks only occurs when passing head-to-wind (Rule 13)
