Again, the purpose of this exercise for me was emergency descent for
collision avoidance.

I missed this point the first time, so I am glad you repeated it.

Of course! To avoid a collision, you do whatever is necessary and you may
have to decide instantaneously and instinctively. That said...

A spiral (even a fast descending spiral) is not my first choice for
collision avoidance because 1) I prefer a strategy that allows me to keep
sight of the aircraft I am avoiding, You just don't know what the other
aircraft is going to do. and... 2) A spiral takes me back near (or to) to
the bit of airspace that contained the other aircraft. That is the last
place where I want to go! (Yes, I know you are descending for avoidance,
but the other pilot may have seen you and made the same choice at the same
moment)

Just my 2 cents for discussion.
