With the FFXIV.Ariyala set, it gives you a total accuracy of: 483. Let's see if the Alpaku Food Buff is actually correct.

483/100=4.83*2 = 9.66 + 483 = 492.66

That isn't 493 accuracy.

It's not good because it doesn't calculate food buffs properly. I'm going to contact the maker of ffxiv.ariyala to fix his food.
