Measuring charts of the same paper twice - once with i1Pro2 (MO), then again with my original i1Pro in an iO table - the first reading reports paper white point as L*94, while the second is L*97. This pattern seems to be consistent for the several matte papers I have read lately.

When the i1 is in the iO it uses different calibration patches, is it possible that one of them is really dirty & the instrument is calibrating differently?
