The good book says "full rudder opposite to the spin(as shown by turn needle). Pause (1 Sec). Control column centrally forward until spin stops.
Move the stick progressively forward until, if necessary, it reaches the fully forward position in about 3 seconds.
I have only reached full forward once, in a T67200 which we subsequently found was right on/ pushing the edge of the C of G envelope.
Stick partly forward is not good enough! Keep it moving and the rotation WILL stop when the wing eventually unstalls.
