Okay, let's clear up exactly how this works.
I want you to think of the fame-raising of this quest in this way.
This quest raises fame only in Selbina.
Bastokan and San d'Orian fame use Selbina fame as a base, so increasing Selbina Fame also increases Bastok/San d'Oria fame.
Rabao uses Bastokan fame as a base. So raising Selbina Fame raises Bastokan Fame raises Rabao Fame.
Jeuno uses a Windurst/Bastok/San d'Oria fame average as a base, so raising Selbina Fame raises Bastok AND San d'Oria fame, but not Windurst fame, so Jeuno fame will go up from this quest, but slower.
This quest DOES NOT AFFECT Norg/Tenshodo fame or Windurst fame, so you have to get those on your own.
