Sigma 35mm 1.4 ART focusing issues - bad copy?

Hey, before I trade the lens in or send it for repair I would like to know if anyone else has this experience. 1/4 shots seems to be out of focus by a huge amount My 50mm sigma art nails focus 100% of the time except when user error. The 35 lens has been calibrated with the sigma dock and it's tack sharp when it does focus but I just can't trust it during a wedding and it's just sitting in my bag.

Do I have a bad copy? I have calibrated it and I stop it down to f2 - use "expand af focus point" (I have tried single focus point too). It keeps missing focus really bad even when there isn't much change with the scene or my position.

Thanks in advance.
