One allowance here buys 72,790 EXP, which places it 5th of the 6 Lv 45 Carpenter tradecraft leves that record EXP. The best of them, Trident and Error, returns 168,310 EXP for the same allowance, 131% more.

Across that rung the return runs from 26,790 EXP to 168,310 EXP per allowance — 6 distinct figures spanning 528%, so the wrong pick leaves 141,520 EXP of the allowance unspent.

On whether to wait: the best Lv 50 Carpenter tradecraft leve returns 334,080 EXP per allowance, 98% more than the best on this rung, while the Lv 40 rung behind tops out at 102,600 EXP.

At Lv 45 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 98,250 EXP per allowance, the 4 Fieldcraft ones 733,026 EXP, which puts this leve 26% below its own category's average.

Jade Crook ×1 is a Lv 44 Carpenter recipe, 2 steps deep through 3 intermediates, costing 7 units of raw material and 23 crystals.

Handing that in returns 10,399 EXP and 50 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Carpenter and Goldsmith.

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 218,370 EXP and 1,044 gil for the 1 allowance it costs, or 218,370 EXP per allowance.
