Exactly right, xil! The idea would be to dial in or morph in a real world chest-waist-hip-cup size measurement in the proper proportion without having to rely on "Looks good to me."

I have a tendency to over do it a little in certain areas, and then the character only appears good from the main cam and zeroed out.

I'm surprised DAZ hasn't listed a corresponding, real world / body inch measurement chart somewhere in their Arcana - along with the breast dial settings at least.
