Nimbus 4DT accident 31 July 2000 in Spain.

Edward Lockhart writes
Its not about how far the wing has dropped, its about whether the
glider has started to rotate about the dropped wing.

I think //that's// the answer the question was looking for.

If you've been slow to intiate the recovery, the glider will start to
yaw/rotate around the dropped wing and once this has happened, your
first action should be full opposite rudder.

Or the nose drop self-corrects the stall and the glider develops into a
spiral dive, in which case centring the controls and kicking in a
boot-full of opposite rudder is only going to delay recovery in the face
of a now rapidly approaching Vne.

Despite knowing the difference, being practised and familiar with the
characteristics, recovery and differences of both, it's the prospect of
mistaking a spiral dive for a spin in the adrenaline rush of the moment
that actually still scares me, despite the fact that I quite enjoy being
upside down in a glider
