dist.new is the file to check, it is the distribution done with the
current potential.  (.pot.cur)

Correct!

If you want to iterate on them more, you can put a <name>.pot.in in
the main directory as an initial guess.
If you don't want to iterate on them more, you just add the final xvg
file to <filelist> and remove their block from settings.xml.
