Interesting. I took some readings of my warranty replacement panel. Yesterday at MRT 2 black level was consistently 0.005 ftL. Today at MRT 18 in measures 0.004 ftL. I expected break in might change it but not this quickly.
I also did a quick and dirty two point only grayscale calibration and while it has the usual crazy error spike at 90 IRE I'd almost swear it looks as good if not better than my old panel looked with its custom ten point adjustments. I'm definitely going with less is more in ten point when I get enough hours on it to dial this one in.
