If you want to further validate the new LUT/profile combination it is much faster as no LUT is written. Since the process is easy you can go back to the home button, change to calibration2 with the OSD, change your settings and repeat the process. Upon quitting the application I have the Unexpectedly Quit warning, yet it has no effect on the profile or calibration. The validation window is a bit confusing too as the selectors for Matrix or LUT profiles, version level, small patch set-large, etc. are still shown whilst you cannot change the validation after the creation of the calibration and profile. The only thing you can select for validation is Average ∆E and Maximum ∆E which range the error reporting pass or fail within the range set.
