What the allowance actually buys
One allowance here buys 7,170 EXP, which places it 6th of the 6 Lv 15 Culinarian tradecraft leves that record EXP. The best of them, A Total Nut Job, returns 19,270 EXP for the same allowance, 169% more.
Across that rung the return runs from 7,170 EXP to 19,270 EXP per allowance — 6 distinct figures spanning 169%, so the wrong pick leaves 12,100 EXP of the allowance unspent.
On whether to wait: the best Lv 20 Culinarian tradecraft leve returns 22,960 EXP per allowance, 19% more than the best on this rung, while the Lv 10 rung behind tops out at 10,480 EXP.
At Lv 15 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 16,554 EXP per allowance, the 4 Fieldcraft ones 78,432 EXP, which puts this leve 57% below its own category's average.
Gil ranks it differently: 173 gil per allowance is 4th of 6 on the same rung against 6th on EXP, with the best there paying 235 gil.
Raw Oyster ×3 is a Lv 19 Culinarian recipe, a single step, costing 2 units of raw material and 2 crystals.
Handing that in returns 3,585 EXP and 87 gil for every unit of raw material the order swallows.
