I posted a 100% completion guide in Site Staff if anyone wants to look at it. It will be made available soon on the Front Site as soon as Site Staff is done with the FFX-2 section. Total percentage of the game is 105% I think. They added the extra percentage so you didn't have to do ALL of the game to get the perfect ending. I got 100% without beating trema or doing the Chocobo dungeon thing on M'ihen High Rd.
