Pretty much max aft elevator (short of the secondary stall - a simplification, but it will do)
Sorry, but in my book this will
NOT "do", fine, you say "short of the secondary stall", but most students trying what you suggest probably
would end up in a secondary stall!
Correct technique after stopping the spin and centralising is to roll wings level and ease out of the dive, as long as this is done in reasonable time there is no need for anywhere near max aft elevator and "G" should stay well below 4, - normally around 2.5-3. Of course with the right aircraft and student the pull out can be delayed to allow something aerobatic of the end of it
then you might get 4G or more, but this is not of course the standard recovery!
