What the allowance actually buys
One allowance here buys 646,380 EXP, the best of the 3 Lv 74 Carpenter tradecraft leves that record EXP: the runner-up manages 387,820 EXP, 40% less.
Across that rung the return runs from 210,060 EXP to 646,380 EXP per allowance — 3 distinct figures spanning 208%, so the wrong pick leaves 436,320 EXP of the allowance unspent.
On whether to wait: the best Lv 76 Carpenter tradecraft leve returns 919,160 EXP per allowance, 42% more than the best on this rung, while the Lv 72 rung behind tops out at 826,240 EXP.
At Lv 74 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 514,135 EXP per allowance, the 3 Fieldcraft ones 1,574,264 EXP, which puts this leve 26% above its own category's average.
White Ash Grinding Wheel ×1 is a Lv 74 Carpenter recipe, 2 steps deep through 3 intermediates, costing 16 units of raw material and 40 crystals.
Handing that in returns 40,399 EXP and 271 gil for every unit of raw material the order swallows, and the tree needs Blacksmith, Carpenter and Goldsmith.
