Yanking the stick back to
neutral to fix the horizon on the canopy at the top of a cable break
recovery qualifies as departing from normal flight conditions.

We agree. This is the reason for the training scenario which teaches
avoidance of this situation.

But I certainly see the problem you face. We train pilots to take note of
a
stick well aft as one sign of an imminent stall. They might not so
quickly recognize that the glider can be stalled with the stick at
neutral under these conditions.

To stop the nose at the normal gliding attitude after a wire break requires
a powerful elevator and full back stick. This is definitely a pilot induced
stall resulting from a mis-use of the elevator. However, accident records
show that this has occasionally been the cause of a spin accident so the
training scenario was added. To repeat what I wrote earlier, this is merely
a slight variant of an accelerated stall. If the stick were held neutral,
the nose would fall through to a steep nose down attitude. This is not the
best technique but it wouldn't result in a deep stall.

I found it difficult, in practice, to pull the stick back far enough to
park the nose on the horizon. Very couterintuitive (for me, at least),
though I can see how any pilot at low altitude might let a canopy full
of terrain misinform his better judgement.

BTW, throughout a dozen or more of these maneuvers, the glider never
spun. I'll give details. And remember, the point of the exercise wasn't
to show how misapplied controls might cause a sudden spin (this was
more than clear throughout the maneuver), but what would happen if I
paid accute attention to coordination.
