What the allowance actually buys
One allowance here buys 17,230 EXP, which places it 6th of the 6 Lv 30 Culinarian tradecraft leves that record EXP. The best of them, Bloody Good Tart, This, returns 72,430 EXP for the same allowance, 320% more.
Across that rung the return runs from 17,230 EXP to 72,430 EXP per allowance — 6 distinct figures spanning 320%, so the wrong pick leaves 55,200 EXP of the allowance unspent.
On whether to wait: the best Lv 35 Culinarian tradecraft leve returns 79,780 EXP per allowance, 10% more than the best on this rung, while the Lv 25 rung behind tops out at 55,060 EXP.
At Lv 30 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 44,832 EXP per allowance, the 4 Fieldcraft ones 275,323 EXP, which puts this leve 62% below its own category's average.
Cornmeal ×4 is a Lv 29 Culinarian recipe, a single step, costing 3 units of raw material and 3 crystals.
Handing that in returns 5,743 EXP and 23 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 51,690 EXP and 207 gil for the 1 allowance it costs, or 51,690 EXP per allowance.
