What the allowance actually buys
One allowance here buys 219,640 EXP, which places it 3rd of the 3 Lv 68 Alchemist tradecraft leves that record EXP. The best of them, Ultimate Official Strategy Guide, returns 681,530 EXP for the same allowance, 210% more.
Across that rung the return runs from 219,640 EXP to 681,530 EXP per allowance — 3 distinct figures spanning 210%, so the wrong pick leaves 461,890 EXP of the allowance unspent.
On whether to wait: the best Lv 70 Alchemist tradecraft leve returns 693,190 EXP per allowance, 2% more than the best on this rung, while the Lv 66 rung behind tops out at 625,040 EXP.
At Lv 68 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 550,185 EXP per allowance, the 3 Fieldcraft ones 1,189,544 EXP, which puts this leve 60% below its own category's average.
Enchanted Palladium Ink ×1 is a Lv 68 Alchemist recipe, a single step, costing 5 units of raw material and 5 crystals.
Handing that in returns 43,928 EXP and 126 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 658,920 EXP and 1,893 gil for the 1 allowance it costs, or 658,920 EXP per allowance.
