I repeated the test with some rough DIY, an aluminum straight profile with a piece of black taper as a target for the AF system then the ruler aligned on the 20 mark with the black marker and a series of shots from -20 to +20 with +- 5 increments from negative to positive.

I am satisfied this test is hardly near the standard needed for critical testing.

Now, tests aside, the fact is that in real life shooting focus is not consistent at all,

Exactly- but is it the camera - or not using a good test subject/

Let me please know what you think about it

Not much - as you have not used a set-up suitable for critical testing.

In lots of ways good photography is much more about how equipment is used rather than anything else.
