The DotTune video was interesting, thanks for the link.

But I'm still unclear about fine tuning a zoom. Do you fine tune for just one FL and if so, which FL?

I'm probably the wrong person to answer this, since I've yet to even attempt to FT a zoom. From what I've read, most folks that are using FT on zooms, do it on the focal length that they most use. But, that depends greatly on which zoom and what you're trying to do, I think. I know of one person that has a book of settings for each lens, at different focal lengths, under different lighting conditions. So, he's at one extreme while I'm at the other.  But, most of the zooms that I use, are already as accurate as I need, so maybe that's not a fair comparison.

Nikon doesn't have a good FT system for zooms.  Canon allows for 2 distinct settings, per lens, on some of their cameras, which is much better for a zoom.  It's probably a safe assumption that Nikon will follow their lead in future cameras.
