What the allowance actually buys
One allowance here buys 1,425,640 EXP, the best of the 3 Lv 76 Leatherworker tradecraft leves that record EXP: the runner-up manages 919,160 EXP, 36% less.
Across that rung the return runs from 551,490 EXP to 1,425,640 EXP per allowance — 3 distinct figures spanning 159%, so the wrong pick leaves 874,150 EXP of the allowance unspent.
On whether to wait: the best Lv 78 Leatherworker tradecraft leve returns 1,606,520 EXP per allowance, 13% more than the best on this rung, while the Lv 74 rung behind tops out at 937,250 EXP.
At Lv 76 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 754,791 EXP per allowance, the 3 Fieldcraft ones 1,812,275 EXP, which puts this leve 89% above its own category's average.
Zonureskin Coat of Maiming ×1 is a Lv 77 Leatherworker recipe, 4 steps deep through 7 intermediates, costing 37 units of raw material and 61 crystals.
Handing that in returns 38,531 EXP and 124 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Blacksmith, Leatherworker and Weaver.
