As I thought: nowhere does it say it "cannot recover from a spin without
pulling the parachute and did not do so in tests". It says "has not been
demonstrated". There's a subtle but important difference.

Bull. That's no difference at all.

Bull? Bull yourself. It's a huge difference.

I have never demonstrated that I am capable of driving a car into a brick
wall. Does that mean that I am actually not capable of driving a car into a
brick wall?

No, of course it doesn't.

Lack of demonstration doesn't not in and of itself imply lack of ability.
