What the allowance actually buys
One allowance here buys 214,460 EXP, which places it 3rd of the 3 Lv 70 Blacksmith tradecraft leves that record EXP. The best of them, Fire Sale, returns 693,190 EXP for the same allowance, 223% more.
Across that rung the return runs from 214,460 EXP to 693,190 EXP per allowance — 3 distinct figures spanning 223%, so the wrong pick leaves 478,730 EXP of the allowance unspent.
On whether to wait: the best Lv 72 Blacksmith tradecraft leve returns 954,450 EXP per allowance, 38% more than the best on this rung, while the Lv 68 rung behind tops out at 806,710 EXP.
At Lv 70 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 433,208 EXP per allowance, the 3 Fieldcraft ones 1,302,824 EXP, which puts this leve 50% below its own category's average.
Gil ranks it differently: 1,920 gil per allowance is 2nd of 3 on the same rung against 3rd on EXP, with the best there paying 3,840 gil.
Deepgold Nugget ×1 is a Lv 71 Blacksmith recipe, a single step, costing 5 units of raw material and 6 crystals.
Handing that in returns 42,892 EXP and 384 gil for every unit of raw material the order swallows.
