What the allowance actually buys
One allowance here buys 1,606,520 EXP, the best of the 3 Lv 78 Leatherworker tradecraft leves that record EXP: the runner-up manages 1,103,750 EXP, 31% less.
Across that rung the return runs from 783,880 EXP to 1,606,520 EXP per allowance — 3 distinct figures spanning 105%, so the wrong pick leaves 822,640 EXP of the allowance unspent.
On whether to wait: the best Lv 80 Leatherworker tradecraft leve returns 935,000 EXP per allowance, 42% less than the best on this rung, while the Lv 76 rung behind tops out at 1,425,640 EXP.
At Lv 78 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 955,432 EXP per allowance, the 3 Fieldcraft ones 2,129,178 EXP, which puts this leve 68% above its own category's average.
Swallowskin Jacket of Scouting ×1 is a Lv 78 Leatherworker recipe, 3 steps deep through 7 intermediates, costing 29 units of raw material and 58 crystals.
Handing that in returns 55,397 EXP and 167 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Goldsmith, Leatherworker and Weaver.
