I seem to have better luck getting good focus every other shot when a subject is coming towards me. Center spot or 5 point makes little difference. The camera isn't ready on the first shot and hasn't figured out how fast the subject is moving. Hits it on the second, overshoots the focus on the third, settles in pretty much after that. If you need the first image in a rapid fire mode to be sharp, start holding the AF button down a second or three as the subject approaches, then start shooting.
Not claiming these are foolproof or will work for everything, but for running dogs, it works for me.
