I forgot to mention the distance is "stable" only if you already start
at it - then we keep it. But start at a higher value, and the distance
keeps growing. Or start at a lower value, and it collapses to 1. Plus
it's rather sensitive, a minor variation can easily push the distance in
either direction.
So it's more like an "unstable equilibrium" in physics.
