What the allowance actually buys
One allowance here buys 556,350 EXP, the best of the 3 Lv 68 Carpenter tradecraft leves that record EXP: the runner-up manages 408,920 EXP, 26% less.
Across that rung the return runs from 180,810 EXP to 556,350 EXP per allowance — 3 distinct figures spanning 208%, so the wrong pick leaves 375,540 EXP of the allowance unspent.
On whether to wait: the best Lv 70 Carpenter tradecraft leve returns 565,870 EXP per allowance, 2% more 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 1% above its own category's average.
Zelkova Necklace ×1 is a Lv 69 Carpenter recipe, 3 steps deep through 5 intermediates, costing 18 units of raw material and 30 crystals.
Handing that in returns 30,908 EXP and 146 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Carpenter and Weaver.
