Thanks for your stats of AF repeatability JoJu, I hope you realize I don't want to go down the road of Sigma vs Nikon reliability pe se, It looks like you are getting a very high success rate with both Nikon and Sigma personally I would be very happy with that!
One thing though is the reported miss-focus shots all came from a distance of more than three meters, more from 5 mts to infinity, but rest assured I won't ask you to test those scenarios.
Here is a typical thread,

My point is just calling attention to the amount of complainants and general observations, I cannot say anything constructive beyond that, other than I have taken on board the PDAF vs PDCDAF debate.
Just to add to the débâcle, here's Jason Lanier's video of the Metabones adapter and the Canon 70-200mm F2.8L on the Sony A7RII.
If I was younger and richer, if...I would probably go there!
