What the allowance actually buys
One allowance here buys 258,410 EXP, which places it 3rd of the 3 Lv 78 Culinarian tradecraft leves that record EXP. The best of them, A Happy End, returns 828,030 EXP for the same allowance, 220% more.
Across that rung the return runs from 258,410 EXP to 828,030 EXP per allowance — 3 distinct figures spanning 220%, so the wrong pick leaves 569,620 EXP of the allowance unspent.
On whether to wait: the best Lv 80 Culinarian tradecraft leve returns 724,620 EXP per allowance, 12% less than the best on this rung, while the Lv 76 rung behind tops out at 689,550 EXP.
At Lv 78 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 955,432 EXP per allowance, the 3 Fieldcraft ones 2,129,178 EXP, which puts this leve 73% below its own category's average.
Coffee Biscuit ×3 is a Lv 79 Culinarian recipe, 2 steps deep through 2 intermediates, costing 11 units of raw material and 27 crystals.
Handing that in returns 23,492 EXP and 119 gil for every unit of raw material the order swallows.
The record carries a repeats value of 2. This site reads that as 2 further turn-ins on the same leve — an assumption, because the source data defines no meaning for the field — which would put the ceiling at 775,230 EXP and 3,930 gil for the 1 allowance it costs, or 775,230 EXP per allowance.
