I had troubles getting consistent AFMA results once and I had to change the process. I found that consistently shooting in the same spot was my challenge. Here's the process (bear with me) that I used.
-Mount the camera to your tripod and level it out
-Tether the camera to your PC.
-Mount the lens align target on a tripod and level it out. I get it as close as possible to MFD. Ideally, you have an old tripod that has a crank to raise and lower it.
-Open the EOS utility and go to live shooting.
-Click test shot.
-Zoom to x1
-If the scroll bar on the side of the test shot lines up in the middle, great. If not, raise and lower the target until you achieve this. (see pic below)
-From there, you can adjust the AFMA. I was VERY delicate when pushing the buttons so as not to move the camera.
-Keep it tethered throughout the adjustment process so there is no variation.
This helped me to get consistent results. If you're doing this already, my apologies. Just offering up a solution that helped me.
