What the allowance actually buys
One allowance here buys 72,600 EXP, the best on the Lv 35 Alchemist tradecraft rung — matched exactly by 1 other leve of the 6 there, with the rest trailing at 64,750 EXP or less.
Across that rung the return runs from 38,850 EXP to 72,600 EXP per allowance — 4 distinct figures spanning 87%, so the wrong pick leaves 33,750 EXP of the allowance unspent.
On whether to wait: the best Lv 40 Alchemist tradecraft leve returns 94,280 EXP per allowance, 30% more than the best on this rung, while the Lv 30 rung behind tops out at 41,410 EXP.
At Lv 35 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 61,959 EXP per allowance, the 4 Fieldcraft ones 378,392 EXP, which puts this leve 17% above its own category's average.
Embossed Book of Silver ×1 is a Lv 38 Alchemist recipe, 3 steps deep through 4 intermediates, costing 15 units of raw material and 25 crystals.
Handing that in returns 4,840 EXP and 65 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Goldsmith and Weaver.
