What the allowance actually buys
One allowance here buys 40,730 EXP, which places it 4th of the 6 Lv 40 Alchemist tradecraft leves that record EXP. The best of them, Arcane Arts for Dummies, returns 94,280 EXP for the same allowance, 131% more.
Across that rung the return runs from 20,000 EXP to 94,280 EXP per allowance — 5 distinct figures spanning 371%, so the wrong pick leaves 74,280 EXP of the allowance unspent.
On whether to wait: the best Lv 45 Alchemist tradecraft leve returns 106,480 EXP per allowance, 13% more than the best on this rung, while the Lv 35 rung behind tops out at 72,600 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 44% below its own category's average.
Gil ranks it differently: 484 gil per allowance is 3rd of 6 on the same rung against 4th on EXP, with the best there paying 637 gil.
Shark Oil ×1 is a Lv 41 Alchemist recipe, a single step, costing 2 units of raw material and 5 crystals.
Handing that in returns 20,365 EXP and 242 gil for every unit of raw material the order swallows.
