What the allowance actually buys
One allowance here buys 94,450 EXP, which places it 5th of the 6 Lv 58 Armorer tradecraft leves that record EXP. The best of them, Sir, Dost Thou Even Heft, returns 811,360 EXP for the same allowance, 759% more.
Across that rung the return runs from 15,742 EXP to 811,360 EXP per allowance — 6 distinct figures spanning 5054%, so the wrong pick leaves 795,618 EXP of the allowance unspent.
On whether to wait: the best Lv 60 Armorer tradecraft leve returns 594,520 EXP per allowance, 27% less than the best on this rung, while the Lv 56 rung behind tops out at 534,960 EXP.
At Lv 58 this data holds 54 leves paying EXP across 2 categories: the 48 Tradecraft ones average 327,945 EXP per allowance, the 6 Fieldcraft ones 716,251 EXP, which puts this leve 71% below its own category's average.
Adamantite Rivets ×1 is a Lv 58 Blacksmith recipe, 2 steps deep through 1 intermediate, costing 6 units of raw material and 10 crystals.
Handing that in returns 15,742 EXP and 68 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 283,350 EXP and 1,218 gil for the 1 allowance it costs, or 283,350 EXP per allowance.
