Cupid's bow depth
How deep the dip of the Cupid's bow sits below its peaks, in millimeters. A visible but moderate bow gives the upper lip definition; very shallow bows read flat and very deep ones exaggerated.
What counts as ideal
The ideal band is 2.3 mm to 4.0 mm for both men and women. A reading anywhere inside the band scores a full 10.
Ideal range
2.3 mm to 4.0 mm
How it is scored
Everything inside the band scores 10, and the penalty accelerates the further a reading falls outside it rather than dropping off a cliff at the edge. For the male band, the falloff is measured against bounds of 0.5 mm and 5.8 mm: a reading out at either of those has spent its full allowance and scores about 3. The curve keeps going past them, so an extreme reading still separates from a merely poor one.
Cupid's bow depth is one of 67 measurements in the harmony pillar. No single measurement decides a face: each one contributes its own shortfall to a weighted mean, and one hopeless measurement costs a full measurement's worth and never more.
