You are lucky. I got a lemon.
Sounds like after sending it into Canon once it is well within the normal range of MFA. So I wouldn't really call that a 'lemon'. 'Lemon' implies that it had many reoccuring issues and required multiple repairs.

I have tried using the DotTune method of MFA, but never worked. You are making a very valid point, I will try doing it at the site where I take baseball pictures. Thank you
Eh. I don't know how well doing it at the site where you take baseball pictures will work out. Do you have the instructions memorized? It took going through the steps to make one adjustment before I got it memorized, meaning I could come back the next day and do it on another lens without looking up the video again.
Accurately knowing your distances between the camera and the focusing target is crucial for good results. I don't know how well that would work out at your baseball field. I strongly suggest that you try it according to the instructions in the video.
When you take your time, it really works well. Do a web search for a focusing target, so that you can print it out. Making adjustments at a given focal length, but too close, or too far, from the target throws of the AFMA completely.
