What the allowance actually buys
One allowance here buys 257,640 EXP, which places it 3rd of the 3 Lv 62 Alchemist tradecraft leves that record EXP. The best of them, Official Strategy Guide, returns 595,710 EXP for the same allowance, 131% more.
Across that rung the return runs from 257,640 EXP to 595,710 EXP per allowance — 3 distinct figures spanning 131%, so the wrong pick leaves 338,070 EXP of the allowance unspent.
On whether to wait: the best Lv 64 Alchemist tradecraft leve returns 379,020 EXP per allowance, 36% less than the best on this rung, while the Lv 60 rung behind tops out at 812,920 EXP.
At Lv 62 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 417,590 EXP per allowance, the 3 Fieldcraft ones 1,118,055 EXP, which puts this leve 38% below its own category's average.
Potent Spiritbond Potion ×3 is a Lv 62 Alchemist recipe, a single step, costing 5 units of raw material and 6 crystals.
Handing that in returns 51,528 EXP and 99 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 772,920 EXP and 1,488 gil for the 1 allowance it costs, or 772,920 EXP per allowance.
