New AF MA micro adjust method: DotTune

I own a 7D but unfortunately it's not with me. I did all my testing on a 5DM3, which DotTunes very well. It's hard for me to troubleshoot without a 7D in my hands unfortunately. Can you give me a sense of what the VF confirmation feedback was like for the confirmed range you found? Did any of the tune values have any lag between the shutter half-press and green dot, even if only a tiny lag? Did you get any flickering green in the 5 seconds for any of those confirmed values?
