Autofocus correct or not?

Need expert advice.

I recently bought this sigma 24-70mm f2.8 for my canon 6D. Ever since I bought,  I have been facing all this front and back focussing issues. I sent my lens and camera for adjustment (twice infact). Now I got the lens and camera back (microadjusted at +5 at tele).

I still see front focusing issues with some of the photographs I took. Sigma is not agreeing. I am using DPP to check if the focus is at rectangle focus area that I focused at.

Here is some sample images uploaded to dropbox

All are center focused.  Could anyone tell me if these photos are correctly focused or not?

I need a public opinion. If you need I have a whole lot of other images I shared with Sigma.

Canon EOS 6D
