We need the software to have capability in reporting to interpolate lift and slew values between regression points. Because currently when a complex alignment end point is between regression points the reporting only picks up the lift and slew values at the last regression point that is within the alignment extents and copy's and pastes those values for the final few metres of alignment beyond this regression point. This is not a true representation of where the alignment is in relation to the existing regression line. We need the functionality in reporting so that the software interpolates lift and slew values between regression points (even if that regression point is beyond alignment extents) to ensure reporting is accurate for the final few metres of an alignment.
