Nope just the opposite - at near cruise at altitude and a steep bank ' windup' turn at edge of normal- extreme flight envelope

Go look up satguru stuff or seattle times

Thats why only .6 degrees change in stab was needed. But at low speeds, they needed more deflection- changed it by a factor of 4- never notified FAA re the 2.4 degree whack.
Thank you, that is interesting. So it was just the other way around. That also makes more sense with regards to the need to extend MCAS authority.
