Clearly there are questions with respect to NAS that need answering.
The solution is not for everyone/anyone to ring up Dick and ask him to explain it.
If things were explained properly in the first instance, Dick would not have to do the personal job.
Perhaps Mike Smith from the NAS Team might like to take the questions and consider them as the type of subject matter that needs to be addressed in the Education Program/further consdieration of NAS?
I'm not trying to defend Dick here. I believe the questions should be answered. Seeing Dick chooses not to, perhaps Mike Smith can.
