What the allowance actually buys
One allowance here buys 102,600 EXP, which places it 2nd of the 6 Lv 40 Leatherworker tradecraft leves that record EXP — a figure 1 other leve on the rung matches exactly. The best of them, Not So Alike in Dignity, returns 125,680 EXP for the same allowance, 22% more.
Across that rung the return runs from 17,230 EXP to 125,680 EXP per allowance — 5 distinct figures spanning 629%, so the wrong pick leaves 108,450 EXP of the allowance unspent.
On whether to wait: the best Lv 45 Leatherworker tradecraft leve returns 137,400 EXP per allowance, 9% more than the best on this rung, while the Lv 35 rung behind tops out at 94,160 EXP.
At Lv 40 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 72,545 EXP per allowance, the 4 Fieldcraft ones 560,212 EXP, which puts this leve 41% above its own category's average.
Boarskin Culottes ×1 is a Lv 41 Leatherworker recipe, 3 steps deep through 3 intermediates, costing 8 units of raw material and 27 crystals.
Handing that in returns 12,825 EXP and 80 gil for every unit of raw material the order swallows, and the tree needs Leatherworker and Weaver.
