Also, only use the focuspoint in center.
While that may be good advise for a K-3 it is not for tracking in general so much. With an array of focus points that can be assigned a priority, you should, if all goes well, get more in focus of a moving object that may be hard to track. With a single point, tracking and shooting at max FPS, the first time the single point is off the subject or happens to be on a spot that has poor contrast for focusing you can miss the shot.
With an array of focus points under the same situation you have other points to pick up focus if the center goes off the subject or falls on a no contrast part of the subject or scene. This would increase your chances of focus. And ideally your camera should let you tell the array how to behave. For example, give the array outside the center point priority to the nearest or furthest in its field or average the results of all.
