Same here. I settled on my ideal settings a year back, (pretty much maxed on what counts) so as amazing as the tool is, I don't need it. As for black levels, I like my black levels, but this seems to vary for different people and hmds.
Also see no difference in SS .75/hmd 2.0 and ss 1.0/hmd 1.5. never understood why one would downsample ss from default 1.0 and then compensate by increasing hmd, but a few have claimed they like it better. a chacun son gout.
