What the allowance actually buys
One allowance here buys 290,850 EXP, which places it 2nd of the 3 Lv 70 Culinarian tradecraft leves that record EXP. The best of them, Meet for Meat, returns 509,840 EXP for the same allowance, 75% more.
Across that rung the return runs from 290,630 EXP to 509,840 EXP per allowance — 3 distinct figures spanning 75%, so the wrong pick leaves 219,210 EXP of the allowance unspent.
On whether to wait: the best Lv 72 Culinarian tradecraft leve returns 713,410 EXP per allowance, 40% more than the best on this rung, while the Lv 68 rung behind tops out at 466,220 EXP.
At Lv 70 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 433,208 EXP per allowance, the 3 Fieldcraft ones 1,302,824 EXP, which puts this leve 33% below its own category's average.
Frantoio Oil ×3 is a Lv 71 Culinarian recipe, a single step, costing 5 units of raw material and 6 crystals.
Handing that in returns 58,170 EXP and 384 gil for every unit of raw material the order swallows.
