The only way I know to answer that is with the answer above.
The only n that has any value is the last n.  And the only use
of that "n" is as I stated.  It is decremented at each hop until
it gets to zero.  I don't know any other way to answer your
question.  That is it. That is all there is too it.

Please re read my answer.  It agrees with you.  Except that
there is an ambiguity that could imply to others that you are
using one more hop than you are, and why would anyone want to
leave themselves open for criticism due to an ambiguity.    Bob,
