What the allowance actually buys
One allowance here buys 72,600 EXP, the best on the Lv 35 Alchemist tradecraft rung — matched exactly by 1 other leve of the 6 there, with the rest trailing at 64,750 EXP or less.
Across that rung the return runs from 38,850 EXP to 72,600 EXP per allowance — 4 distinct figures spanning 87%, so the wrong pick leaves 33,750 EXP of the allowance unspent.
On whether to wait: the best Lv 40 Alchemist tradecraft leve returns 94,280 EXP per allowance, 30% more than the best on this rung, while the Lv 30 rung behind tops out at 41,410 EXP.
At Lv 35 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 61,959 EXP per allowance, the 4 Fieldcraft ones 378,392 EXP, which puts this leve 17% above its own category's average.
Gil ranks it differently: 192 gil per allowance is 4th of 6 on the same rung against 1st on EXP, with the best there paying 972 gil.
Blinding Potion ×3 is a Lv 36 Alchemist recipe, 2 steps deep through 1 intermediate, costing 4 units of raw material and 9 crystals.
Handing that in returns 18,150 EXP and 48 gil for every unit of raw material the order swallows.
