What the allowance actually buys
One allowance here buys 41,630 EXP, the best of the 6 Lv 25 Leatherworker tradecraft leves that record EXP: the runner-up manages 36,390 EXP, 13% less.
Across that rung the return runs from 18,490 EXP to 41,630 EXP per allowance — 6 distinct figures spanning 125%, so the wrong pick leaves 23,140 EXP of the allowance unspent.
On whether to wait: the best Lv 30 Leatherworker tradecraft leve returns 67,730 EXP per allowance, 63% more than the best on this rung, while the Lv 20 rung behind tops out at 24,710 EXP.
At Lv 25 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 31,772 EXP per allowance, the 4 Fieldcraft ones 204,269 EXP, which puts this leve 31% above its own category's average.
Toadskin Jacket ×1 is a Lv 30 Leatherworker recipe, 2 steps deep through 2 intermediates, costing 7 units of raw material and 11 crystals.
Handing that in returns 5,947 EXP and 80 gil for every unit of raw material the order swallows.
