What the allowance actually buys
One allowance here buys 200,450 EXP, which places it 3rd of the 3 Lv 50 Alchemist tradecraft leves that record EXP. The best of them, Summoning for Dummies, returns 334,080 EXP for the same allowance, 67% more.
Across that rung the return runs from 200,450 EXP to 334,080 EXP per allowance — 3 distinct figures spanning 67%, so the wrong pick leaves 133,630 EXP of the allowance unspent.
On whether to wait: the best Lv 52 Alchemist tradecraft leve returns 480,670 EXP per allowance, 44% more than the best on this rung, while the Lv 45 rung behind tops out at 106,480 EXP.
At Lv 50 this data holds 54 leves paying EXP across 3 categories: the 24 Tradecraft ones average 238,216 EXP per allowance, the 3 Fieldcraft ones 834,862 EXP and the 27 Grand Company ones 132,961 EXP, which puts this leve 16% below its own category's average.
Void Glue ×1 is a Lv 51 Alchemist recipe, a single step, costing 5 units of raw material and 3 crystals.
Handing that in returns 40,090 EXP and 50 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 601,350 EXP and 744 gil for the 1 allowance it costs, or 601,350 EXP per allowance.
