The vertical shift range (in inches) is determined by the size of your screen which you don't mention. As you say the manual states that the vertical shift range is 65% of the screen height.
Example: 100" (16:9) screen has a height of 49"
Vertical shift is 31.85" (above or below the screen surface)
Example: 120" (16:9) screen has a height of 59"
Vertical shift is 38.35" (above or below the screen surface)
So you can see you have plenty of vertical range for most conventional installations.
From the Projector Reviews website:
PT-AR100U Lens Shift
This Panasonic has plenty of lens shift as well as lens flexibility ! For that same 100 inch screen, the PT-AR100U can be placed, (normal or inverted), anywhere from about 32 inches above the top of the screen surface, all the way down to 32 inches below the bottom of the screen surface. That is measured from the center of the lens. There is also a good amount of horizontal lens shift. Using horizontal lens shift will partially limit the range of the vertical lens shift (and vice versa).
The combination of the wide range zoom lens, plenty of lens shift, gives you the flexibility to ceiling mount or shelf mount the PT-AR100U in almost all room situations.
