In this 10-minute segment, I get roughly 8.7 million gil and 8840 AP. In a typical 2-hour run at this, about that of a full loop, I get nearly 100 million gil's worth. Each "All" materia sells for 1.4 million gil when mastered and only takes 35,000 AP to master. This is a whopping 40:1 ratio. Put the alls on a double-growth weapon or armor and this increases to an 80:1 ratio. On triple growth, it's 120:1, the highest possible. I have two characters dedicated for the sole purpose of obtaining gil at this extreme rate. 9 slots of double growth filled with alls. That's 720 gil per AP there alone! There are two others on normal growth weapons and one in a triple growth. That's 920 gil per AP in "all" materia. HP pluses have an 11.2 to 1 ratio and 3 are used to make it 33.6 per AP total. Magic plus has a 28:1 ratio, the next highest after "all" from what I've seen. For this "junk materia" as I call it (materia with no purpose except gil-making), this totals 981.6 gil per AP....
