Select this option if you want to order the alternatives based on their distance from the anchor alternative. The original confidence is ignored and a new confidence is assigned depending on the distance between the alternative and the anchor alternative. Alternatives that are directly next to the anchor alternative would get a confidence of 100% and the further away they are, the lower their confidence.
