Sky Is the Limit

One allowance here buys 109,390 EXP, which places it 5th of the 6 Lv 52 Goldsmith tradecraft leves that record EXP. The best of them, Sense of Entitlement, returns 629,850 EXP for the same allowance, 476% more.

Across that rung the return runs from 18,232 EXP to 629,850 EXP per allowance — 6 distinct figures spanning 3355%, so the wrong pick leaves 611,618 EXP of the allowance unspent.

On whether to wait: the best Lv 54 Goldsmith tradecraft leve returns 647,060 EXP per allowance, 3% more than the best on this rung, while the Lv 50 rung behind tops out at 334,080 EXP.

At Lv 52 this data holds 54 leves paying EXP across 2 categories: the 48 Tradecraft ones average 251,119 EXP per allowance, the 6 Fieldcraft ones 576,023 EXP, which puts this leve 56% below its own category's average.

Mythrite Ingot ×1 is a Lv 52 Blacksmith recipe, 2 steps deep through 1 intermediate, costing 10 units of raw material and 6 crystals.

Handing that in returns 10,939 EXP and 27 gil for every unit of raw material the order swallows.

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 328,170 EXP and 810 gil for the 1 allowance it costs, or 328,170 EXP per allowance.
