It's been nearly two decades since I had that conversation with Dr. 
Raney.  As I noted earlier, and as Jacque and Peter confirm, it's likely 
I was just mistaken - it seems the actual rule is even simpler:

   The defaultStack is the topmost stack with the lowest mode.

Unless you've experienced a problem with it, just keep doing what you're 
doing.  It seems to be working as expected for most people in most 
circumstances.  We have more posts here exploring its definition than 
about problems relating to its behavior.
