I feel like I'm going a bit crazy. I keep seeing guides tell me that I should have no problems getting to 900+ GP with lvl 90 gear, but with a full afflatus accessory set I'm still only at 879. I've even melded materia to things for more! As far as I can find these are the highest level gathering accessories out right now, so, what am I doing wrong?

PLEASE tell me my silly mistake, I am BEGGING. It's taking me ages to gather for the splendorous tools and I hate it, please.
