Not sure if it was here or elsewhere that the author and testers determined that when you get to the point where the AF green dot flickers or delays then you went too far. It can do that for 3 or more values - negative or positive.
The last value where the green dot shows AF lock instantly is the stopping point. If the next value flickers or hesitates even for a bit use the previous value. Not sure if the members that are having mixed results are following this. It happened to me when I did not stop and kept going until there was no AF confirmation at all. Negative side was consistent but the positive side was +16 one time and +20 the next.
I have yet to test this but Fred Miranda at FM forums stated it appeared more accurate.
Thanks for the information. I've been testing this till the AF confirmation is no longer available and have been getting incorrect results.
I'll test again and see what happens.
