What the allowance actually buys
One allowance here buys 154,140 EXP, which places it 3rd of the 3 Lv 52 Alchemist tradecraft leves that record EXP. The best of them, Steeling the Knife, Steeling the Mind, returns 480,670 EXP for the same allowance, 212% more.
Across that rung the return runs from 154,140 EXP to 480,670 EXP per allowance — 3 distinct figures spanning 212%, so the wrong pick leaves 326,530 EXP of the allowance unspent.
On whether to wait: the best Lv 54 Alchemist tradecraft leve returns 647,060 EXP per allowance, 35% more than the best on this rung, while the Lv 50 rung behind tops out at 334,080 EXP.
At Lv 52 this data holds 54 leves paying EXP across 3 categories: the 24 Tradecraft ones average 337,743 EXP per allowance, the 3 Fieldcraft ones 868,208 EXP and the 27 Grand Company ones 177,755 EXP, which puts this leve 54% below its own category's average.
Holy Water ×3 is a Lv 52 Alchemist recipe, a single step, costing 4 units of raw material and 3 crystals.
Handing that in returns 38,535 EXP and 68 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 462,420 EXP and 810 gil for the 1 allowance it costs, or 462,420 EXP per allowance.
