Whenever you leave a ranked dungeon (one of the time trial objective dungeons), you lose 1% of that's world "land share" or "goddess share" (something like that) to an "Other" category. Also, whenever Neptune dies, you lose 1% of that world's land/goddess share to the "Other category" as well. When you complete events on a certain world, you gain a certain portion of the share back by taking it away from the three other worlds. However, it's nearly impossible to get anything back from the Others category. You can get a little bit back, but if you die too many times or if you leave a ranked dungeon without completing it too many times, you can lock yourself out of events for later in the game, because certain events only open up when you get to 50% land/goddess shares in that area.
I was trying to find a good wiki article for you to take a look at, since you might have a better grasp of it, having played the game before, but that's my understanding. Mostly just from reading the trophy map on PS3T.
