What the allowance actually buys
One allowance here buys 339,520 EXP, which places it 2nd of the 3 Lv 70 Goldsmith tradecraft leves that record EXP. The best of them, Satisfactory Sewing, returns 693,190 EXP for the same allowance, 104% more.
Across that rung the return runs from 148,250 EXP to 693,190 EXP per allowance — 3 distinct figures spanning 368%, so the wrong pick leaves 544,940 EXP of the allowance unspent.
On whether to wait: the best Lv 72 Goldsmith tradecraft leve returns 826,240 EXP per allowance, 19% more than the best on this rung, while the Lv 68 rung behind tops out at 681,530 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 22% below its own category's average.
Gil ranks it differently: 1,040 gil per allowance is 3rd of 3 on the same rung against 2nd on EXP, with the best there paying 3,840 gil.
Hematite Earrings of Healing ×1 is a Lv 71 Goldsmith recipe, 3 steps deep through 5 intermediates, costing 22 units of raw material and 36 crystals.
Handing that in returns 15,433 EXP and 47 gil for every unit of raw material the order swallows, and the tree needs Blacksmith and Goldsmith.
