correct me if I am wrong, but I question the value of averaging, particularly with only a couple of sets, that is not weighted averaging. Measuretool used to do this, i1 does not. Any bad patch measurement can throw your standard averaging off unnecessarily. Those with more spreadsheet knowledge than I may be able to do this anyway, but i1 is simple averaging as far as I know. Many devices are averaging a number of measurements per patch as they go anyway, so other than finding problems across the width of a press, with several placed charts, I wonder what help this really is?
