What the allowance actually buys
One allowance here buys 6,840 EXP, which places it 2nd of the 6 Lv 5 Weaver tradecraft leves that record EXP — a figure 1 other leve on the rung matches exactly. The best of them, Just for Kecks, returns 8,460 EXP for the same allowance, 24% more.
Across that rung the return runs from 5,730 EXP to 8,460 EXP per allowance — 4 distinct figures spanning 48%, so the wrong pick leaves 2,730 EXP of the allowance unspent.
On whether to wait: the best Lv 10 Weaver tradecraft leve returns 13,090 EXP per allowance, 55% more than the best on this rung, while the Lv 1 rung behind tops out at 2,740 EXP.
At Lv 5 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 4,554 EXP per allowance, the 4 Fieldcraft ones 28,481 EXP, which puts this leve 50% above its own category's average.
Amateur's Breeches ×1 is a Lv 10 Weaver recipe, 3 steps deep through 3 intermediates, costing 7 units of raw material and 8 crystals.
Handing that in returns 977 EXP and 20 gil for every unit of raw material the order swallows, and the tree needs Leatherworker and Weaver.
