Version 1.6.1 seems to have fixed this problem (hopefully that means you actually changed something!). For example, on version 1.6.0, twenty averages produced: X-rite values of: 5.86, -0.14, 1.84 Spotread values of: 5.63, -0.29, 2.44 However version 1.6.1 produced: X-rite values of: 5.90, -0.10, 1.68 Spotread values of: 5.93, -0.09, 1.68 (not comparable with earlier test since different area of patch) So all is well.
