John, you found the definition in RRS 13 While Tacking.  The rule defines when a tack starts (passing HTW) and when a tack is completed (close-hauled course). Between those two a boat is tacking and does not have right of way. She has changed from port to starboard or starboard to port, as per the definition, but has not regained rights of a boat that has completed her tack.  

In example 2 at position 7 she has not completed her tack before crossing the finish line so she has not executed 44.2. The intent is the penalty is completed before she finishes. I don't believe she has completed her penalty before finishing.

In example 1, I am not fully understanding your description. The hailing boat: "she is sailing close-hauled or above.  When the response is "You Tack" the hailing boat shall tack as soon as possible.  The hailed boat may have to alter course to allow the hailing boat room to tack.  They have told the hailing boat that there is room to tack.
 

Which will convince me better that you were anxious.

"I hailed Starboard. They ignored me. I hailed louder again shouting you need to tack too. They ignored me. I altered course"

"I wasn't sure if they saw me and I was anxious so I altered course"

Can you expand on this?

John, I am glad that the WASZP rules are working in practice.  I think that the wingfoils will go a different direction, with little or no limitations, at least in part because they are always in the standing position.  I think that should be up to the fleet decide and adopt in their class rules so we shall see as the class matures.

I'm with Phillip, in the definition its a measure, and that measure should be consistent. A less than competent crew is not entitled to more room than an expert one, and would be breaking a rule if they require it (lets leave room made freely available out of it for now).  Similarlty an expert crew is allowed the same room as a competent one, even though they may not need it,

John, I agree with you about reasonable apprehension and skill level, but I think its a red herring in the context of Room and Case 103.
