What the allowance actually buys
One allowance here buys 182,320 EXP, which places it 3rd of the 6 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 25,691 EXP to 480,670 EXP per allowance — 6 distinct figures spanning 1771%, so the wrong pick leaves 454,979 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 2 categories: the 48 Tradecraft ones average 251,119 EXP per allowance, the 6 Fieldcraft ones 576,023 EXP, which puts this leve 27% below its own category's average.
Gil ranks it differently: 749 gil per allowance is 2nd of 6 on the same rung against 3rd on EXP, with the best there paying 811 gil.
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.
