2R roundness
2*radius roundness_<angle> is the doubled maximum difference of girdle radius values within the sector of <angle> degrees.
The maximum absolute difference of radius measurements within the sector of <angle> degrees is considered. The maximum of this value over all directions, multiplied by 2, is the 2*radius roundness (<angle>).

The Appraiser Editor, Symmetry tab, contains just the values measured at 11.25°, 22.5°, 45°, and 90°, denoted 2RRoundness_<angle>.
Diameter roundness
Diameter roundness at <angle> is the difference of girdle diameters between the directions at an angle of <angle> degrees.
Diameter is measured in two directions at an angle of <angle> degrees and the absolute difference of these measurements is considered. The maximum of this value over all directions is the Diameter Roundness (<angle>).
