Firstly you would need to have a comparison with a vibration chart showing a MLU version.
Also, it is impossible to tell appart vibrations caused by the mirror and those from the shutter it self. Those peaks during the expose time may well come from the shutter.
Additionaly, the vibration pattern changes when the shutter is closed, which indicates the shutter is playing an important role.
In my opinion the shown chart does not prove or disprove the advantages of MLU.
