As part of that experiment, measure the vertical distance from the guitar top to the bottom of the straight edge, adjacent to the bridge, while at full string tension. Repeat with no string tension. Observe the difference in vertical measurement.

Many luthiers include in their never-before-strung layout some allowance for how much the top will rise when subject to string tension. About 1/16" is a commonly used value, in my experience.
