What the allowance actually buys
One allowance here buys 341,890 EXP, which places it 3rd of the 3 Lv 72 Goldsmith tradecraft leves that record EXP. The best of them, Slimming Down, returns 826,240 EXP for the same allowance, 142% more.
Across that rung the return runs from 341,890 EXP to 826,240 EXP per allowance — 3 distinct figures spanning 142%, so the wrong pick leaves 484,350 EXP of the allowance unspent.
On whether to wait: the best Lv 74 Goldsmith tradecraft leve returns 937,250 EXP per allowance, 13% more than the best on this rung, while the Lv 70 rung behind tops out at 693,190 EXP.
At Lv 72 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 590,811 EXP per allowance, the 3 Fieldcraft ones 1,405,338 EXP, which puts this leve 42% below its own category's average.
Diaspore Bracelet of Slaying ×1 is a Lv 73 Goldsmith recipe, 3 steps deep through 4 intermediates, costing 20 units of raw material and 41 crystals.
Handing that in returns 17,095 EXP and 55 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 1,025,670 EXP and 3,324 gil for the 1 allowance it costs, or 1,025,670 EXP per allowance.
