Does anyone else have the Sigma USB dock yet?

I just got mine it, and I have updated my firmware. However, I don't know exactly how one would proceed to fine tune the focus. Google doesn't seem to know either.

All that really does is show you HOW to make the adjustments but I'm not really sure exactly how you figure out WHAT adjustment to make.
