What the allowance actually buys
One allowance here buys 1,182,260 EXP, the best of the 3 Lv 68 Leatherworker tradecraft leves that record EXP: the runner-up manages 806,710 EXP, 32% less.
Across that rung the return runs from 559,130 EXP to 1,182,260 EXP per allowance — 3 distinct figures spanning 111%, so the wrong pick leaves 623,130 EXP of the allowance unspent.
On whether to wait: the best Lv 70 Leatherworker tradecraft leve returns 820,510 EXP per allowance, 31% less than the best on this rung, while the Lv 66 rung behind tops out at 739,840 EXP.
At Lv 68 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 550,185 EXP per allowance, the 3 Fieldcraft ones 1,189,544 EXP, which puts this leve 115% above its own category's average.
Gazelleskin Corselet of Scouting ×1 is a Lv 69 Leatherworker recipe, 3 steps deep through 8 intermediates, costing 44 units of raw material and 53 crystals.
Handing that in returns 26,870 EXP and 79 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Blacksmith, Goldsmith, Leatherworker and Weaver.
