The Thriller of Autumn (L)

At 10 allowances a run, this leve's 560,140 EXP works out to 56,014 EXP per allowance, which places it 3rd of the 3 Lv 54 Armorer Grand Company leves that record EXP. The best of them, Rage against the Scream (L), returns 260,272 EXP for the same allowance, 365% more.

Across that rung the return runs from 56,014 EXP to 260,272 EXP per allowance — 3 distinct figures spanning 365%, so the wrong pick leaves 204,258 EXP of the allowance unspent.

On whether to wait: the best Lv 56 Armorer Grand Company leve returns 294,229 EXP per allowance, 13% more than the best on this rung, while the Lv 52 rung behind tops out at 305,396 EXP.

At Lv 54 this data holds 54 leves paying EXP across 3 categories: the 27 Grand Company ones average 205,186 EXP per allowance, the 3 Fieldcraft ones 938,680 EXP and the 24 Tradecraft ones 400,590 EXP, which puts this leve 73% below its own category's average.

Titanium Mail of Fending ×1 is a Lv 55 Armorer recipe, 3 steps deep through 6 intermediates, costing 34 units of raw material and 33 crystals.

Handing that in returns 16,475 EXP and 34 gil for every unit of raw material the order swallows, and the tree needs Armorer, Blacksmith, Goldsmith, Leatherworker and Weaver.

The record carries a repeats value of 5. This site reads that as 5 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 3,360,840 EXP and 7,020 gil for the 10 allowances it costs, or 336,084 EXP per allowance.
