Making Ends Meet

One allowance here buys 301,890 EXP, which places it 3rd of the 3 Lv 72 Alchemist tradecraft leves that record EXP. The best of them, Make It Bigger, returns 698,030 EXP for the same allowance, 131% more.

Across that rung the return runs from 301,890 EXP to 698,030 EXP per allowance — 3 distinct figures spanning 131%, so the wrong pick leaves 396,140 EXP of the allowance unspent.

On whether to wait: the best Lv 74 Alchemist tradecraft leve returns 937,250 EXP per allowance, 34% more than the best on this rung, while the Lv 70 rung behind tops out at 693,190 EXP.

At Lv 72 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 590,811 EXP per allowance, the 3 Fieldcraft ones 1,405,338 EXP, which puts this leve 49% below its own category's average.

Superior Spiritbond Potion ×3 is a Lv 72 Alchemist recipe, a single step, costing 5 units of raw material and 12 crystals.

Handing that in returns 60,378 EXP and 222 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 905,670 EXP and 3,324 gil for the 1 allowance it costs, or 905,670 EXP per allowance.
