Improving on the vibrations of the focal plane shutter

I understand the data.  The issue is does it affect photography in a way that can be easily seen in the same way as Mirror slap can. Looking at the examples and data you linked...the answer is no. You must pixel peep at extremely high magnifications to see it so, at this time, it appears that shutter vibration is not a concern regards current photography in the same way Mirror Slap is. Compared to the effects of camera shake....the affects of shutter vibration are non-existent. Shutter vibration exists...but normally can't be seen except in unrealistic high magnification examples...... if I understand you testing correctly.

In other words....the effects of Shutter Vibration are not normally seen in real world photography.  Is that not correct?
