Interestingly, I have had more focus misses with the lens wide open.

That's because the results of either a missed focus or BF/FF mis-adjustment are usually much more obvious with shallow DOF.

In addition to the fact that wide open photography more usually occurs in lower light.  That said, on a DSLR, the lens focuses wide open, regardless.
