What the allowance actually buys
One allowance here buys 127,600 EXP, which places it 3rd of the 3 Lv 56 Leatherworker tradecraft leves that record EXP. The best of them, Don't Sweat the Small Fry, returns 534,960 EXP for the same allowance, 319% more.
On whether to wait: the best Lv 58 Leatherworker tradecraft leve returns 593,380 EXP per allowance, 11% more than the best on this rung, while the Lv 54 rung behind tops out at 560,140 EXP.
At Lv 56 this data holds 54 leves paying EXP across 3 categories: the 24 Tradecraft ones average 390,755 EXP per allowance, the 3 Fieldcraft ones 1,032,386 EXP and the 27 Grand Company ones 195,640 EXP, which puts this leve 67% below its own category's average.
Dragon Leather ×1 is a Lv 56 Leatherworker recipe, a single step, costing 4 units of raw material and 5 crystals.
Handing that in returns 31,900 EXP and 90 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 382,800 EXP and 1,083 gil for the 1 allowance it costs, or 382,800 EXP per allowance.
