Looks like "dispcal -v -d 1 -c 1 -m -q h -t 5000 -b 40 -g 2.4 -B 0.2 -H" {High quality, high resolution spectrum mode} is going to take a while. In iteration 4 with 96 sample points for initial calibration curves, each patch seems to be read for around 70 seconds. That's great! Not complaining! I have often wished the profilers I've used in the past had a "take a really long time" mode. Even if the accuracy of the profile is increased just a little bit, I think it's fantastic! Running two monitors, I was doing a few things on the other display. Something popped up over the color display window. I moved it away within a few seconds. Not sure if that invalidates the profile creation, or whether dispcal is designed to throw out a few seconds of garbage in a 70 second reading. (Guess I'm sort of asking if it's operating in a mean, median, or mode .. mode.) I know the safe thing to do is restart dispcal and don't use my computer while it's running. Reason I'm posting this is I'm interested in comparing the results from a bunch of settings, so would love to know if I have to do that at a time I can walk away from my computer, or if I can do other stuff as long as I move anything that pops up quickly.
