What the allowance actually buys
One allowance here buys 47,200 EXP, the best of the 6 Lv 25 Weaver tradecraft leves that record EXP: the runner-up manages 41,630 EXP, 12% less.
Across that rung the return runs from 24,980 EXP to 47,200 EXP per allowance — 4 distinct figures spanning 89%, so the wrong pick leaves 22,220 EXP of the allowance unspent.
On whether to wait: the best Lv 30 Weaver tradecraft leve returns 99,220 EXP per allowance, 110% more than the best on this rung, while the Lv 20 rung behind tops out at 28,010 EXP.
At Lv 25 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 31,772 EXP per allowance, the 4 Fieldcraft ones 204,269 EXP, which puts this leve 49% above its own category's average.
Velveteen Shirt ×1 is a Lv 26 Weaver recipe, 3 steps deep through 4 intermediates, costing 10 units of raw material and 10 crystals.
Handing that in returns 4,720 EXP and 32 gil for every unit of raw material the order swallows, and the tree needs Leatherworker and Weaver.
