What the allowance actually buys
One allowance here buys 28,010 EXP, the best on the Lv 20 Weaver tradecraft rung — matched exactly by 3 other leves of the 6 there, with the rest trailing at 16,800 EXP or less.
Across that rung the return runs from 12,960 EXP to 28,010 EXP per allowance — 3 distinct figures spanning 116%, so the wrong pick leaves 15,050 EXP of the allowance unspent.
On whether to wait: the best Lv 25 Weaver tradecraft leve returns 47,200 EXP per allowance, 69% more than the best on this rung, while the Lv 15 rung behind tops out at 24,790 EXP.
At Lv 20 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 17,352 EXP per allowance, the 4 Fieldcraft ones 113,304 EXP, which puts this leve 61% above its own category's average.
Cotton Doublet Vest of Gathering ×1 is a Lv 23 Weaver recipe, 3 steps deep through 4 intermediates, costing 8 units of raw material and 8 crystals.
Handing that in returns 3,501 EXP and 44 gil for every unit of raw material the order swallows, and the tree needs Goldsmith, Leatherworker and Weaver.
