OK, N/A... on the other subject - I compared a new black velvet sample measuring with i1pro2 and spectrolino : i1pro2 gives L* = ~2.9-~4.0 on various spots and spectrolino ~2.9-~3.5 on various spots... so I guess if both of them do measure noticeably lighter black patches on SG and their data is similar then so it is... new targets do have the black patches lighter... I did not hear back from X-Rite so far... so will be trying to remind them again, albeit w/o big hope.
Yes, it seems they need to publish a new reference for SG. Or recognise bad batches and either replace, or publish references. One other thing - if you have polarasing filter for Spectrolino, try measuring with the filter on, using MeasureTool from ProfileMaker 5.0.10. It should not make a difference, theoretically, but does not hurt to try.
Very sorry I confused you with Spectrolino / ColorPort.
