1. I change between one down to slow and Zero all the time depending upon what I am needing in focal speed. If I am shooting a pan shot at 90 degrees to a subject then I use a slow tracking speed. If I am shooting a 1/1500 or faster I step up the Focal speed to one step faster than zero so it can track the AF quicker as the bike moves towards me or away.
3. I selected 1 here because since I am shooting in a AF Spot mode, then Main focus Point priority is redundant. So I give continuous AF Track Priority so that it can find that point and lock it.
4. Selected 1 here so that if it cannot find the subject, it does not continue to hunt. Eventually as my subject is moving in my pan shot it will be in focus and I will pull the trigger on the shot. 9 out of 10 it hits perfect now.
5. I adjusted my lenses and only think it makes me feel better. This setting seems to change more than my girlfriend's moods.
6. Totally disabled the Multi-zone focal points. i will select what I want where I want.
12. I selected different points so when I change the landscape to portrait mode it already has the focal point where I need it.

1. My Shutter button half-press is set for metering start, not focus!
The AF-ON is set for Metering & AF Start. The rest are default I think.
To get the tack sharp images I track an object through its movement towards or away from me with the AF On button pressed. As I am ready for the kill... I pull the trigger to capture the shot. This does not force the camera to recompose by having to adjust due to movement of the subject. That is what the tracking is for.
Seems to be working for me.
