I have manually focussed on numerous occasions now, and can see that it is in focus, so why would an auto focus system be any better? I have live magnification of the moving image, remember.
Advice has been given by a number of people but you seem to want to dismiss it out of hand?
In my previous post those were observations of your responses, not criticism based upon your responses. You have stated yourself you prefer manual focus, yet when it has been recommended you try different approaches, you state you prefer your own. It seems to be a paradox for anyone trying to help you.

Yes, you heard right - the autofocus could not always focus on the badge, despite it being made the prime focus point.
I don't know what modes you are referring to but autofocus does not guarantee focus, instead it improves the reliability of getting an in focus shot if used in a practiced manner. Like I said before, if you are shooting a bunch of images in a row, then some portion will be in focus, and you use those.
One last point regarding live view manual focussing hand held, it is like juggling, trying to hold the camera away from your body is not a very stable platform and will contribute to focus drift and camera blur issues. If you held the camera against your face, looking through the viewfinder, that will provide a stabler shooting platform. Live view focusing is really useful if you have the camera in stable fixed position, like on a tripod where you can really nail the focus. But off the tripod, the camera is subject to swaying back and forth, side to side and becomes a challenge to achieving focus. And even if you think you've nailed the focus in live view hand held, there's a fraction of second delay between engaging the shutter release and the exposure which will provide the opportunity for an offset in the focus.
