System overestimates the circumference when the manual trace function is used. the trace circumference value is overestimated; however, the area value is accurate. the issue is present in Sequoia's VA20A/VA25 onward as the VA20A introduced a new calculation design that did not include an optimization step of discarding pixel points that are too close together, causing the close pixel points into the accumulated circumference/distance value makes the final value highly sensitive to small trackball motions.
