Yes I was. Per my lab I set my computer to 6500K and 100 lum. I had to turn my brightness way down to match my prints. I know you said that there was little to do to adjust color with this calibrator. The lab recommended I adjust my Kelvin manually to match the color. I had to adjust my Kelvin down to 5200K to match the yellow tint in the images.
Could that be my issue? (By your comments I fear I way more than marginally off ? Is it color, brightness, all of it?)
I have 5 sessions to edit and am not sure how to proceed.
With regards to resigning up for the class: you mentioned antiquated sliders in your last post, does the new class have info for new versions?
