Interesting! So a stall will always occur at the same stick position if the weight and balance is the same. So what about loading then? The speed at which a stall will occur is more relevant - and this speed will change at the square root of the load factor. At 1g, if the stalling speed of an aircraft is 60 knots, at 2g, it will be 60 x 1.4 = 84 knots, at 4g it will be 60 x 2 = 120 knots. At 0g, the aircraft will not stall. I suggest that in each of these cases the stick position will be very different.
As for 'walking the rudder' in a stall, enough has been mentioned here for me to not go into why this is not sensible.
I hope you're not teaching your students this nonsense - assuming you're an instructor. Which I hope you're not!
