One allowance here buys 67,730 EXP, which places it 2nd of the 6 Lv 30 Weaver tradecraft leves that record EXP. The best of them, By the Short Hairs, returns 99,220 EXP for the same allowance, 46% more.

Across that rung the return runs from 34,430 EXP to 99,220 EXP per allowance — 6 distinct figures spanning 188%, so the wrong pick leaves 64,790 EXP of the allowance unspent.

On whether to wait: the best Lv 35 Weaver tradecraft leve returns 115,720 EXP per allowance, 17% more than the best on this rung, while the Lv 25 rung behind tops out at 47,200 EXP.

At Lv 30 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 44,832 EXP per allowance, the 4 Fieldcraft ones 275,323 EXP, which puts this leve 51% above its own category's average.

Gil ranks it differently: 473 gil per allowance is 1st of 6 on the same rung against 2nd on EXP, with the best there paying 473 gil.
