I noticed you took the test shots in AF-C iso AF-S, so I suspect your camera was still in "picture mode" iso "test shot mode" so to speak. Could it be that single focus point wasn't set either? With AF-C & multipoint, you don't know exactly where the camera focuses on, certainly if you didn't use single focus point. And, more importantly, the camera refocuses even if you use single point in AF-C mode. I had the same experience and took the shots again after setting the camera into calibration mode
Recommendation: use one of the memory banks for calibration purposes only. This will save quite some time, and avoid mistakes, like I also made.
You have to shoot wide open, otherwise the target will appear too sharp because of the larger DOF, even when it is not in focus due to a particular AFA. Michael recommends sharpness Off for the same reason (and contrast to max). Use f/8 only if it is difficult to see the alignment, and use it in color mode. I have set Vivid to a high sharpness, high contrast, and Monochrome to 0 sharpness and high contrast for taking test shots.
