What the allowance actually buys
One allowance here buys 2,297,800 EXP, the best of the 2 Lv 88 Carpenter tradecraft leves that record EXP: the runner-up manages 1,457,380 EXP, 37% less.
On whether to wait: the best Lv 90 Carpenter tradecraft leve returns 1,440,660 EXP per allowance, 37% less than the best on this rung, while the Lv 86 rung behind tops out at 2,028,020 EXP.
At Lv 88 this data holds 18 leves paying EXP across 2 categories: the 16 Tradecraft ones average 1,852,163 EXP per allowance, the 2 Fieldcraft ones 3,242,290 EXP, which puts this leve 24% above its own category's average.
Gil ranks it differently: 5,020 gil per allowance is 2nd of 2 on the same rung against 1st on EXP, with the best there paying 5,040 gil.
Integral Magitek Rod ×1 is a Lv 88 Carpenter recipe, 3 steps deep through 5 intermediates, costing 33 units of raw material and 80 crystals.
Handing that in returns 69,630 EXP and 152 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Carpenter, Goldsmith and Leatherworker.
