You need to move the part being dropped very close to the base where it drops onto to reduce the running time of the travel to the base.

The End Time should be long enough to cover its travel time to the base and the event duration of the drop impact. 

In your model, I suggest the End Time = 0.005 sec or 0.01 sec or longer, depending upon how far is the distance between the dopped part and the base.
