Accuracy

Is calculated by comparing each suspension point's length change to the main line's overall change after re-measurement. Deviations over 3.0mm from the average are considered noticeable and may distort the trim result.

In-group deviations

Readings that are more than 10mm away from each other within one group.
This could be a sign of inaccurate measuring setup/technique or swapped line map points.

Trim

Groups arranged behind each other in flight direction having more than 10mm deviation. 

This should be corrected.

Group deviations

Groups that are more than 20mm away from measurement baseline.
The measurement baseline is the median (-22) of the deviations of all measurements from their nominal values.
