What the allowance actually buys
One allowance here buys 1,509,210 EXP, the best of the 3 Lv 78 Weaver tradecraft leves that record EXP: the runner-up manages 1,403,790 EXP, 7% less.
Across that rung the return runs from 598,990 EXP to 1,509,210 EXP per allowance — 3 distinct figures spanning 152%, so the wrong pick leaves 910,220 EXP of the allowance unspent.
On whether to wait: the best Lv 80 Weaver tradecraft leve returns 935,000 EXP per allowance, 38% less than the best on this rung, while the Lv 76 rung behind tops out at 1,425,640 EXP.
At Lv 78 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 955,432 EXP per allowance, the 3 Fieldcraft ones 2,129,178 EXP, which puts this leve 58% above its own category's average.
Dwarven Cotton Gaskins of Fending ×1 is a Lv 78 Weaver recipe, 3 steps deep through 5 intermediates, costing 25 units of raw material and 51 crystals.
Handing that in returns 60,368 EXP and 194 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Leatherworker and Weaver.
