I understand the difference and knew the stretch I was making. Did so for clarity with mud? (grin) The point I was heading for though was the attenuation is not fast in terms of energy lost to the medium. The waves attenuate as a function of changing media and refractions and reflections from those changes. All of which takes time.

Look at ocean waves for a more valid example with little loss in energy when traveling completely across an ocean even when traveling across the paths of other wave trains.

And we agree completely on the need to shoot the bullet in a place where the damage kills quickly.
