The SweetLine parameter description, information about its calculation and presence in appraisers and reports is presented on the SweetLine page.
Parameter Usage
Using the SweetLine parameter, you can achieve better optical performance for the solutions. Smaller values of SweetLine would cut out a stripe from the rectangle, potentially enabling the search for favorable solutions over a wide range of parameters. Previously this area could only be covered by a series of smaller rectangles, that is, by running the search multiple times with extremely tightened CrownAngle and PavilionAngle, each time covering a small portion of the stripe. Sweetline offers a less time-consuming alternative to this approach.

Yellow Flags = SR above solution #1, Modern_Cut with Table EX = [54 60]
Green Flags = the same with SweetLine EX = [-0,3 0,3]
