Hi Jim,
              Absolutely correct.   Depending on the inertial of a given 
hammer, and the force of the blow, it causes the shank to first bend, 
before the hammer is set in motion.
SloMo studies of action parts conclusively show that the hammer rarely hits 
the string square on.
The whip lash of the shank, will cause the hammer to slightly over or under 
centre.

Regards Roger
