Many prop "strikes" are not sudden stoppages. Like when the prop slices
through a tow bar or digs a little ditch in the dirt. The Lyc and TCM
instructions, however, are that any incident that damages the prop to any
extent that cannot be repaired by simple gravel nick-filing requires a
teardown. Which seems like crazy overkill to me.

I can see that a sudden stoppage, a la WHANG! - (silence), might break
something inside.

When the engine is started it goes from barely turning to suddenly
spinning
fast. Why can't it take a faster than normal deceleration from a prop
flailing against pavement or bashing a tow bar?

The difference is whether the acceleration or deceleration is constant or
sudden.
