Do you also open the (black) box to see how Schroedinger's cat is doing?

I do whatever I need to do to solve the problem, Gene.
If I have to open the box to see if the cat is dead
or alive, that's what I will do. I do not believe in
erecting silly artificial barriers in the quest for
knowledge - and we are not talking about a quantum
physics paradox.

So let me repeat: The phase shifts at the -j567 points
in the two following 1/4WL stubs are not the same.

--43.4 deg 600 ohm line--+--46.6 deg 600 ohm line--open

--43.4 deg 600 ohm line--+--10 deg 100 ohm line--open

The phase shift at '+' in the 1st example is zero.

The phase shift at '+' in the 2nd example is 36.6 deg.
