Girdle Verticality
Alias: GirdleVerticality
Girdle facets average slope deviation from vertical in degrees.
Calculation
Thу larger area the facet with the deviation from vertical has the more it affects visually the stone. That is why the areas of the Girdle facets are includedintothe calculation.

Girdle Slope Deviation Max
Alias: GirdleSlopeDeviationMax
Maximum girdle facet slope deviation from GirdleVerticality in degrees.
Calculation
We take every Girdle facet, calculate its deviation from vertical (A-90), then compare it to average deviation from vertical (GirdleVerticality) for this stone, then from all found values we select the maximum. It is GirdleSlopeDeviationMax.
