Code:

+        var += ssd - ((sad/16) * (sad/16));
I win.

That will fail because i?6:8 compensates for the different sizes of the SSDs in different planes, while your code does not.

That makes a fixed sensitivity almost impossible, maybe an automatic sensitivity that can adjust to the input resolution?
This reflects the fact that lower resolutions generally have higher average block variances, since there are more edges and fewer large areas of flat detail.
