It's My Business to Know Things

One allowance here buys 20,000 EXP, which places it 6th of the 6 Lv 40 Goldsmith tradecraft leves that record EXP. The best of them, When We Were Blings, returns 79,510 EXP for the same allowance, 298% more.

Across that rung the return runs from 20,000 EXP to 79,510 EXP per allowance — 5 distinct figures spanning 298%, so the wrong pick leaves 59,510 EXP of the allowance unspent.

On whether to wait: the best Lv 45 Goldsmith tradecraft leve returns 137,400 EXP per allowance, 73% more than the best on this rung, while the Lv 35 rung behind tops out at 72,600 EXP.

At Lv 40 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 72,545 EXP per allowance, the 4 Fieldcraft ones 560,212 EXP, which puts this leve 72% below its own category's average.

Red Coral Armillae ×1 is a Lv 40 Goldsmith recipe, a single step, costing 3 units of raw material and 9 crystals.

Handing that in returns 6,667 EXP and 86 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 60,000 EXP and 777 gil for the 1 allowance it costs, or 60,000 EXP per allowance.
