What the allowance actually buys
One allowance here buys 489,060 EXP, the best of the 3 Lv 64 Blacksmith tradecraft leves that record EXP: the runner-up manages 425,480 EXP, 13% less.
Across that rung the return runs from 185,340 EXP to 489,060 EXP per allowance — 3 distinct figures spanning 164%, so the wrong pick leaves 303,720 EXP of the allowance unspent.
On whether to wait: the best Lv 66 Blacksmith tradecraft leve returns 625,040 EXP per allowance, 28% more than the best on this rung, while the Lv 62 rung behind tops out at 705,130 EXP.
At Lv 64 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 435,661 EXP per allowance, the 3 Fieldcraft ones 1,139,405 EXP, which puts this leve 12% above its own category's average.
Doman Iron Culinary Knife ×1 is a Lv 65 Blacksmith recipe, 2 steps deep through 3 intermediates, costing 17 units of raw material and 23 crystals.
Handing that in returns 28,768 EXP and 176 gil for every unit of raw material the order swallows, and the tree needs Blacksmith, Carpenter and Goldsmith.
