Thank you for your elucidating explanation/correction. I'm amazed how one continues to learn new 'secrets' of the control system after so much time. What you write makes sense to me, but leaves me with a couple of questions:
I've read somewhere that full back side stick corresponds to a demand of 2.5 g. Suppose you are at 1.3 g with neutral side stick, then pull the stick to the back stop. What do you get?
Then we have this description in mm43's post #366: "With STICK FREE in turbulence, small deviations do occur on the flight path but with a tendancy of the A/C to regain a steady condion". Does that functionality only exist with stick free?

Agreed. I've edited the last sentence of my post.
