This is why I suspect the stall in question was the power on, turning flight at 3kts per second deceleration rate. It is a very aggressive manoeuvre for a jet transport, requiring a high pitch attitude. If the manoeuvre stability is low during the deceleration, the static stability will probably be worse.
