The Wailers' First Law of Potion

One allowance here buys 17,310 EXP, which places it 6th of the 6 Lv 25 Alchemist tradecraft leves that record EXP. The best of them, You Put Your Left Hand In, returns 43,600 EXP for the same allowance, 152% more.

Across that rung the return runs from 17,310 EXP to 43,600 EXP per allowance — 6 distinct figures spanning 152%, so the wrong pick leaves 26,290 EXP of the allowance unspent.

On whether to wait: the best Lv 30 Alchemist tradecraft leve returns 41,410 EXP per allowance, 5% less than the best on this rung, while the Lv 20 rung behind tops out at 21,600 EXP.

At Lv 25 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 31,772 EXP per allowance, the 4 Fieldcraft ones 204,269 EXP, which puts this leve 46% below its own category's average.

Hi-Potion ×3 is a Lv 25 Alchemist recipe, 2 steps deep through 1 intermediate, costing 3 units of raw material and 5 crystals.

Handing that in returns 5,770 EXP and 42 gil for every unit of raw material the order swallows.

The record carries a repeats value of 2. This site reads that as 2 further turn-ins on the same leve — an assumption, because the source data defines no meaning for the field — which would put the ceiling at 51,930 EXP and 378 gil for the 1 allowance it costs, or 51,930 EXP per allowance.
