[QUOTE="nickt, post: 355505, member: 4923"] I think I understand his point. I can see how 51 pts might get distracted and maybe that delay would be helpful. I think it could happen with single point too. I can't remember exactly what I did, but I convinced myself that having a delay set was detrimental to keeping focus on a bird. Also detrimental to keep track on my kid when she was playing field hockey. I have no hard data for you though. I'm usually in single point or 9 point and I have shied away from 51pt. I think the issue was when the subject was heading towards me. I can't remember, lost brain cells, lol. I'm pretty sure that delay keeps af-c from making a correction too soon once focus is acquired. This could be fine for side to side movement, but not good for a subject charging at you. I understand your angst. Its tough to wrap your mind around the intricacies of the Af system.
