Thanks both!

Yeah, there's actually a formulation for optimal distribution of windings to minimize or equalize losses; it's kind of goofy, but with 3D printers available these days, not terribly far-fetched.

Geez, I know it used to be public, but I can't find it!  Anyone know what I'm talking about?  Did they pull it down?

Could it be this?

YEA!  That was the one!

More for Litz than regular, I suppose, but probably not terrifically different results as long as you're still using relatively fine wire (as compared to the bobbin size).
