PJ2's sim pitched down with "full forward stick applied and held (...) from an AoA of 40deg to 10deg (in) 24 seconds", i.e. at an agonizingly slow rate of 1.25 deg/second. How are you going to improve on that? Using manual trim might help, but see Dozy's post #1096. Pulling the thrust levers back to idle would help to increase the ND pitching moment, but that's about all I can think of.

In this initial phase of recovery the sim is performing outside the envelope of known aerodynamic data from flight test or windtunnel. It is possible that actual airplane performs better. On page 111, at 02:12:45 in TOGA and with the THS at -13.8 deg, the airplane pitches down in response to a short push on the stick at 2.7 deg/second, and again at 02:13:30 at CLB thrust.
