Cap It Off

One allowance here buys 333,810 EXP, which places it 3rd of the 3 Lv 68 Weaver tradecraft leves that record EXP. The best of them, One Winged Angle, returns 1,057,080 EXP for the same allowance, 217% more.

Across that rung the return runs from 333,810 EXP to 1,057,080 EXP per allowance — 3 distinct figures spanning 217%, so the wrong pick leaves 723,270 EXP of the allowance unspent.

On whether to wait: the best Lv 70 Weaver tradecraft leve returns 820,510 EXP per allowance, 22% less than the best on this rung, while the Lv 66 rung behind tops out at 625,040 EXP.

At Lv 68 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 550,185 EXP per allowance, the 3 Fieldcraft ones 1,189,544 EXP, which puts this leve 39% below its own category's average.

Serge Knit Cap ×1 is a Lv 70 Weaver recipe, 3 steps deep through 4 intermediates, costing 17 units of raw material and 24 crystals.

Handing that in returns 19,636 EXP and 74 gil for every unit of raw material the order swallows, and the tree needs Alchemist and Weaver.

The record carries a repeats value of 2. This site reads that as 2 further turn-ins on the same leve — an assumption, because the source data defines no meaning for the field — which would put the ceiling at 1,001,430 EXP and 3,786 gil for the 1 allowance it costs, or 1,001,430 EXP per allowance.
