A Magnanimous Refrain

One allowance here buys 450,200 EXP, which places it 3rd of the 3 Lv 76 Goldsmith tradecraft leves that record EXP. The best of them, Prophet of Profit, returns 919,160 EXP for the same allowance, 104% more.

Across that rung the return runs from 450,200 EXP to 919,160 EXP per allowance — 3 distinct figures spanning 104%, so the wrong pick leaves 468,960 EXP of the allowance unspent.

On whether to wait: the best Lv 78 Goldsmith tradecraft leve returns 1,103,750 EXP per allowance, 20% more than the best on this rung, while the Lv 74 rung behind tops out at 937,250 EXP.

At Lv 76 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 754,791 EXP per allowance, the 3 Fieldcraft ones 1,812,275 EXP, which puts this leve 40% below its own category's average.

Triplite Earrings of Casting ×1 is a Lv 76 Goldsmith recipe, 3 steps deep through 4 intermediates, costing 21 units of raw material and 54 crystals.

Handing that in returns 21,438 EXP and 79 gil for every unit of raw material the order swallows, and the tree needs Alchemist 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 1,350,600 EXP and 4,971 gil for the 1 allowance it costs, or 1,350,600 EXP per allowance.
