What the allowance actually buys
One allowance here buys 22,960 EXP, the best of the 6 Lv 20 Culinarian tradecraft leves that record EXP: the runner-up manages 22,570 EXP, 2% less.
Across that rung the return runs from 11,880 EXP to 22,960 EXP per allowance — 6 distinct figures spanning 93%, so the wrong pick leaves 11,080 EXP of the allowance unspent.
On whether to wait: the best Lv 25 Culinarian tradecraft leve returns 55,060 EXP per allowance, 140% more than the best on this rung, while the Lv 15 rung behind tops out at 19,270 EXP.
At Lv 20 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 17,352 EXP per allowance, the 4 Fieldcraft ones 113,304 EXP, which puts this leve 32% above its own category's average.
Gil ranks it differently: 277 gil per allowance is 3rd of 6 on the same rung against 1st on EXP, with the best there paying 288 gil.
Honey Muffin ×3 is a Lv 21 Culinarian recipe, 2 steps deep through 3 intermediates, costing 12 units of raw material and 6 crystals.
Handing that in returns 1,913 EXP and 23 gil for every unit of raw material the order swallows.
