The Aroma of Faith

One allowance here buys 145,960 EXP, which places it 3rd of the 3 Lv 50 Culinarian tradecraft leves that record EXP. The best of them, The Next to Last Supper, returns 343,900 EXP for the same allowance, 136% more.

Across that rung the return runs from 145,960 EXP to 343,900 EXP per allowance — 3 distinct figures spanning 136%, so the wrong pick leaves 197,940 EXP of the allowance unspent.

On whether to wait: the best Lv 52 Culinarian tradecraft leve returns 310,610 EXP per allowance, 10% less than the best on this rung, while the Lv 45 rung behind tops out at 126,270 EXP.

At Lv 50 this data holds 54 leves paying EXP across 3 categories: the 24 Tradecraft ones average 238,216 EXP per allowance, the 3 Fieldcraft ones 834,862 EXP and the 27 Grand Company ones 132,961 EXP, which puts this leve 39% below its own category's average.

Baked Onion Soup ×3 is a Lv 52 Culinarian recipe, 3 steps deep through 6 intermediates, costing 19 units of raw material and 24 crystals.

Handing that in returns 7,682 EXP and 14 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 437,880 EXP and 810 gil for the 1 allowance it costs, or 437,880 EXP per allowance.
