Setting the Stage

One allowance here buys 356,710 EXP, which places it 3rd of the 3 Lv 60 Armorer tradecraft leves that record EXP. The best of them, Mail It In, returns 594,520 EXP for the same allowance, 67% more.

Across that rung the return runs from 356,710 EXP to 594,520 EXP per allowance — 3 distinct figures spanning 67%, so the wrong pick leaves 237,810 EXP of the allowance unspent.

On whether to wait: the best Lv 62 Armorer tradecraft leve returns 595,710 EXP per allowance, 0% more than the best on this rung, while the Lv 58 rung behind tops out at 811,360 EXP.

At Lv 60 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 415,953 EXP per allowance, the 3 Fieldcraft ones 1,098,783 EXP, which puts this leve 14% below its own category's average.

High Steel Helm of Maiming ×1 is a Lv 61 Armorer recipe, 3 steps deep through 3 intermediates, costing 18 units of raw material and 14 crystals.

Handing that in returns 19,817 EXP and 50 gil for every unit of raw material the order swallows, and the tree needs Armorer, Blacksmith and Weaver.

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 1,070,130 EXP and 2,703 gil for the 1 allowance it costs, or 1,070,130 EXP per allowance.
