This "test" concludes really nothing.

What I would do is have the subject six feet from the camera. Be sure to use a tripod and set it to the eye level of the subject.  If you shoot manual focus be sure to zoom all the way in and focus that way all focal lengths will be in focus as long as you do Not move the camera.

If focal length is the only variable do not change exposure just focal length.

So, tripod at eye level, lens is six feet from subject.  When you get to the equivalent focal length of about 85 mm you should have a nice head & shoulder portrait.

You do not want to use different focal lengths and just fill the frame with them.

He is doing that to show the different perspective distortion at the different distances (moving is necessary to fill the frame).  I think it amounts to the same thing as what you are describing.  Yes, we all understand that perspectives are determined by distance from the subject, not exactly by FL.

You can repeat from 12 feet back.
