>I'm now 100 percent satisfied that there is a problem.

If you're convinced, then by all means proceed to have it fixed. I hope it is successful.

But here's what I'm getting at - if you are trying to convince people here there is a problem, or want practical advice on what to do about it, you need to give us some better material to work with

The problem there is that the actual AF sensors do not match up exactly with the displayed focus brackets - in particular, the AF sensor is typically larger than the markings. With an angled target, there will be detail at different distances under the same sensor, which leads to unpredictable results. A flat, parallel target eliminates this variable.
