Well, I am not arguing this or that beeing the cause of the crash, I am only speculating as to the effect of an free floating HS.
With that said I really thought the vertical speed increased significantly all the way down to the ground?
If it was at an almost constant flight path angle, then the transition from more or less level flight about 20 sec prior to the aircraft hitting the ground, to the constant nose down angle must have happened extremely quickly and hence required a very high value of negative G for a few sec
