Martin,
I do not think you are missing something.
I agree with you that the procedure mentioned by Eric is a process
conformance result, which is excellent, by any means. Offering a validating
software myself, I would only be careful of not using the same software that
made the calibration for validating ;-)
One of the rationales for using another software is that if you validate
with colors that were used for profiling, there is a better chance of a
better fit at those point in comparison with other randomly selected values.
However, whatever the validating result is, and whatever the software used
to measure it comes from, the average tolerance values have to be taken as
"relative" to the accuracy of the instrument, and the difference between
instruments can be significantly higher.
Eric mentioned he did not have a comparison between the i1 Display and the
i1 Pro; it would be interesting to see the process validation numbers for
the same setups using the i1 Pro (by same setup: same computers, monitors,
OS, profiling program) since they have enough data for good stats.
Ufortunately, this is quite a task to profile so many displays.

Hi Eric and all,
Talking about validation, is the validation done using the same
instrument? If so, I can't see how this validates the instrument. For
sure the conversion process but not the instrument. Am I missing
something?

Hi Marco,
I'm not sure if this is completely on topic as I don't have a comparison
between i1 Displays and i1's. But in a large publishers here in the UK I
set
them up with Eye One Match and i1Displays, running Apple Cinema Displays
mostly 20" and number of 23". Most of the 20" validate .3-.4 dE average,
with the 23" coming in around .5dE. And that is 280 displays calibrating
every 4 weeks.
