Hello, all. This is a very interesting thread.
In my opinion, the way you were doing seems correct to me.
I am having difficulty understanding the recommendation that Everdo areas are not Areas of Focus/Responsibility.
The way I see it, they should be, while context tags support the filtering by physical location.
For reference, I raised this in the original thread too: How to Define and Use Everdo Areas Effectively- Everdo - #11 by LuisNeto .
