shutter shock opinion

i was not really bother about shutter shock but after all these threads and posts i would like to understand better.

since now i've understood that it is most likely to happen between 1/60 up to 1/200.

now i was looking and searching in my library pictures within this range and honestly i can't see any problem.

is this problem constant or it happens randomly?

can i share some pics and ask for your opinion about presence or not of this effect?
