Curiouser and curiouser, said Alice.

It varies with dynamic pressure. Maybe I can mention the term EAS and leave the rest to you?

What an extraordinary view. It appears to me to conflict with your earlier apparent interest in how a wing stalls:

Say you fly in or near a thunderstorm, and get hit with a strong gust. Is it all the same to you if the airplane suddenly pitches up more strongly than you can pitch down, or if your elevators don't appear to function any more to control pitch? Wouldn't it be preferable to have at least a modicum of understanding as to what might be going on, so that you can effect your desire

...... The disconnect is between those who hold a mouse and those who hold a control column, and in my opinion reasonable.
You are welcome to your opinion. Sorry I misjudged you. I had understood from your previous posts that you were interested in what happens with a "fully stalled" wing.
