What the allowance actually buys
One allowance here buys 182,320 EXP, which places it 2nd of the 3 Lv 52 Leatherworker tradecraft leves that record EXP. The best of them, Maybe He's a Lion, returns 480,670 EXP for the same allowance, 164% more.
Across that rung the return runs from 154,140 EXP to 480,670 EXP per allowance — 3 distinct figures spanning 212%, so the wrong pick leaves 326,530 EXP of the allowance unspent.
On whether to wait: the best Lv 54 Leatherworker tradecraft leve returns 560,140 EXP per allowance, 17% more than the best on this rung, while the Lv 50 rung behind tops out at 334,080 EXP.
At Lv 52 this data holds 54 leves paying EXP across 3 categories: the 24 Tradecraft ones average 337,743 EXP per allowance, the 3 Fieldcraft ones 868,208 EXP and the 27 Grand Company ones 177,755 EXP, which puts this leve 46% below its own category's average.
Wyvern Leather ×1 is a Lv 52 Leatherworker recipe, a single step, costing 4 units of raw material and 3 crystals.
Handing that in returns 45,580 EXP and 187 gil for every unit of raw material the order swallows.
