What the allowance actually buys
One allowance here buys 57,210 EXP, which places it 5th of the 6 Lv 45 Alchemist tradecraft leves that record EXP. The best of them, Quit Your Jib-jab, returns 106,480 EXP for the same allowance, 86% more.
Across that rung the return runs from 51,270 EXP to 106,480 EXP per allowance — 4 distinct figures spanning 108%, so the wrong pick leaves 55,210 EXP of the allowance unspent.
On whether to wait: the best Lv 50 Alchemist tradecraft leve returns 334,080 EXP per allowance, 214% more than the best on this rung, while the Lv 40 rung behind tops out at 94,280 EXP.
At Lv 45 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 98,250 EXP per allowance, the 4 Fieldcraft ones 733,026 EXP, which puts this leve 42% below its own category's average.
Gil ranks it differently: 150 gil per allowance is 6th of 6 on the same rung against 5th on EXP, with the best there paying 557 gil.
Mega-Potion of Vitality ×3 is a Lv 46 Alchemist recipe, a single step, costing 3 units of raw material and 11 crystals.
Handing that in returns 19,070 EXP and 50 gil for every unit of raw material the order swallows.
