[argyllcms] R: Re: Difficult in calibration

Yes, now maybe I understand, the reason is the luminance which was too 
low even if Dispcal said 120 cd/m2. Dispcal luminance reading  are not 
in agreement with Xrite software: the same luminance are read by 
dispcal as higher. Why?

Below the DispcalGUI report with its final 
error when has to store the profile in the right folder.

Thank you

Hmm. Setting -v2 doesn't change the code behavior, it 
just
reports more information on what's going on. So any improvement
is 
due to some other reason. One possibility is that the display
may have 
been behaving more repeatedly at the time of this run.

If you are 
compiling from source, you could try lowering
the REFINE_GAIN factor 
defined in dispcal (ie. try 0.5),
and see if this has any effect on 
your situation. Given
that your runs seem to be varying a bit, this 
could be
difficult to judge.
