Some apparatchiks (IMO) over on SO saw this question and Rick's answer to it and were complaining to each other about that
it'd never be allowed on SO (my paraphrase of the sentiment) and would be deleted as Not An Answer there.
Thankfully, one of the people in that discussion came here and actually did the right thing and flagged it, as well as linking to the discussion.
I get it. That's why I edited the answer and added a screen capture of one of the diagrams from the link.
But should it really be deleted as Not An Answer ?
