What the allowance actually buys
One allowance here buys 148,250 EXP, which places it 3rd 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, 368% 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 66% 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.
Hard Mudstone Whetstone ×1 is a Lv 71 Goldsmith recipe, a single step, costing 3 units of raw material and 6 crystals.
Handing that in returns 49,417 EXP and 640 gil for every unit of raw material the order swallows.
