What the allowance actually buys
One allowance here buys 1,525,130 EXP, the best of the 2 Lv 82 Alchemist tradecraft leves that record EXP: the runner-up manages 846,040 EXP, 45% less.
On whether to wait: the best Lv 84 Alchemist tradecraft leve returns 1,746,150 EXP per allowance, 14% more than the best on this rung, while the Lv 80 rung behind tops out at 1,355,750 EXP.
At Lv 82 this data holds 18 leves paying EXP across 2 categories: the 16 Tradecraft ones average 1,208,998 EXP per allowance, the 2 Fieldcraft ones 2,464,410 EXP, which puts this leve 26% above its own category's average.
Luncheon Toadskin Codex ×1 is a Lv 82 Alchemist recipe, 3 steps deep through 5 intermediates, costing 34 units of raw material and 71 crystals.
Handing that in returns 44,857 EXP and 144 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Goldsmith, Leatherworker and Weaver.
