What the allowance actually buys
One allowance here buys 13,090 EXP, the best of the 6 Lv 10 Carpenter tradecraft leves that record EXP: the runner-up manages 9,990 EXP, 24% less.
Across that rung the return runs from 3,780 EXP to 13,090 EXP per allowance — 6 distinct figures spanning 246%, so the wrong pick leaves 9,310 EXP of the allowance unspent.
On whether to wait: the best Lv 15 Carpenter tradecraft leve returns 24,790 EXP per allowance, 89% more than the best on this rung, while the Lv 5 rung behind tops out at 6,840 EXP.
At Lv 10 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 8,265 EXP per allowance, the 4 Fieldcraft ones 43,676 EXP, which puts this leve 58% above its own category's average.
Gil ranks it differently: 230 gil per allowance is 2nd of 6 on the same rung against 1st on EXP, with the best there paying 287 gil.
Ash Spinning Wheel ×1 is a Lv 12 Carpenter recipe, 3 steps deep through 3 intermediates, costing 12 units of raw material and 8 crystals.
Handing that in returns 1,091 EXP and 19 gil for every unit of raw material the order swallows, and the tree needs Blacksmith and Carpenter.
