JVC DLA-RS500U Vertical shift question

First home theatre and first projector. Question regarding vertical shift: is it measured from top of screen to center of lens? Would think so, but just looking for confirmation.

FYI, I am building a motorized vertical and horizontal masking system and want to ensure I mount the projector via a fixed length ceiling mount tube such that the 10 various screen sizes I preset via the lens memory on my JVC RS500 (i.e. BIG 2.35, 1.85, and 1.78 ratios; medium versions and small versions plus one other... Big 2.76?) can all be accommodated with my ceiling mount position. Want to make sure I get it right. Thanks.
