By how much do the three faces differ, measured in shape space?

Which anatomical regions show the most divergence across the three methods?

Which regions are most consistent?

Are there systematic relationships between the methods — for instance, do the two manual methods resemble each other more than they resemble the algorithmic method, or does the pattern of divergence cut differently?

The results of this analysis provided a more structured and precise account of the differences among the three reconstructions than visual inspection alone could yield.

Some regions showed reasonable consistency across methods, reflecting the robust skull data that all three were responding to.
