What the allowance actually buys
One allowance here buys 466,220 EXP, the best of the 3 Lv 68 Culinarian tradecraft leves that record EXP: the runner-up manages 371,080 EXP, 20% less.
Across that rung the return runs from 312,780 EXP to 466,220 EXP per allowance — 3 distinct figures spanning 49%, so the wrong pick leaves 153,440 EXP of the allowance unspent.
On whether to wait: the best Lv 70 Culinarian tradecraft leve returns 509,840 EXP per allowance, 9% more than the best on this rung, while the Lv 66 rung behind tops out at 459,720 EXP.
At Lv 68 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 550,185 EXP per allowance, the 3 Fieldcraft ones 1,189,544 EXP, which puts this leve 15% below its own category's average.
Chirashi-zushi ×3 is a Lv 69 Culinarian recipe, 2 steps deep through 1 intermediate, costing 10 units of raw material and 17 crystals.
Handing that in returns 46,622 EXP and 262 gil for every unit of raw material the order swallows.
