Field Symmetry

How evenly the magnetic field is distributed across all four measurement axes (x-, x+, y-, y+). A high symmetry score means the field strength is nearly identical in all directions from center. That indicates the coil produces a uniform, balanced output. A low score reveals directional bias where some axes are significantly stronger or weaker than others. The report bands the result as Highly Symmetric at 80% and above, Moderately Symmetric from 60% to 80%, and Asymmetric below 60%. The score is calculated by comparing each individual axis reading to the mean of all 4 axes at each distance, weighted by field strength (stronger readings count more). It uses a 15% floor (ignoring weak-field areas below 15% of peak) and a 15% deviation cap. The center reading is shared by all four axes and is excluded from the comparison. Requires all 4 axes. Score = 100 minus weighted average deviation percentage. See Multi-Axis Scan and Mirrored Falloff Profile.
