Yes, that's how I understand it, but of course I am just a patzer.

It is most important in pawn endgames, but it can have some relevance
even in more complex endgames.  It can sometimes be a significant
advantage when you can afford to trade down to a pawn endgame, but
your opponent can't.

I have never had any success with bonuses for outside passed pawns,
not even if I restrict it to pawn endgames.  This could be simply because
I haven't found the right weights, of course.

I do have a small bonus for candidate passers, but I am not sure how
effective it is.
