As flattering as it is to be confused with PJ2, My remark had to do with PF's first input after a/p loss.
With NOSE UP, (and LEFT ROLL), if PF was impatient for NU response after initial pull, he may have accentuated it with more pull. The a/c is heavy, and having taken manual control in these conditions w/o alot of experience (did anyone?), his exaggerated pull may have caught the airframe responding, and been responsible for the 1.6 gee rotation?
The traces tell this?
