What the allowance actually buys
One allowance here buys 662,250 EXP, which places it 3rd of the 3 Lv 78 Goldsmith tradecraft leves that record EXP. The best of them, Bulking Up, returns 1,103,750 EXP for the same allowance, 67% more.
On whether to wait: the best Lv 80 Goldsmith tradecraft leve returns 724,620 EXP per allowance, 34% less than the best on this rung, while the Lv 76 rung behind tops out at 919,160 EXP.
At Lv 78 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 955,432 EXP per allowance, the 3 Fieldcraft ones 2,129,178 EXP, which puts this leve 31% below its own category's average.
Petalite Bracelet of Fending ×1 is a Lv 79 Goldsmith recipe, 3 steps deep through 5 intermediates, costing 26 units of raw material and 62 crystals.
Handing that in returns 25,471 EXP and 67 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 1,986,750 EXP and 5,241 gil for the 1 allowance it costs, or 1,986,750 EXP per allowance.
