Ref post 506 ..

The jet still has a positive static stability, so pushing forward to overcome the control law that keeps trying to achieve one gee would eventually result in a downward vector

This may have been one of the problems confusing PF. Static stability (which is nice to have as it feels right) is to do with stick forces rather than deflection. The basic requirement is that the pilot has to exert a pull force to maintain speed below the trim speed .. ie, release the stick and the nose wants to pitch down.

The description given is akin to neutral or negative static stability which would be quite distressing to most pilots without test experience and much more so to one with limited hands on stick and rudder experience overall, compounded by a life of watching and button pressing ..
