This field is computed by summing the squares of the position error for each time unit on a graph. The lower this value, the closer the actual position curve tracked the target position curve. The numerical value displayed in this field has no meaning by itself, but it can be used during tuning to check whether a tuned parameter was helpful or harmful to the tracking of the position. In order to have a valid comparison the two graphs must have the same length, and the moves need to have had the same target profile. Otherwise, the changed parameter is not isolated in the test.
