What the allowance actually buys
One allowance here buys 649,855 EXP, which places it 3rd of the 3 Lv 54 Fisher fieldcraft leves that record EXP. The best of them, Analysis of Paralysis, returns 1,083,092 EXP for the same allowance, 67% more.
On whether to wait: the best Lv 56 Fisher fieldcraft leve returns 1,191,215 EXP per allowance, 10% more than the best on this rung, while the Lv 52 rung behind tops out at 1,001,778 EXP.
At Lv 54 this data holds 54 leves paying EXP across 3 categories: the 3 Fieldcraft ones average 938,680 EXP per allowance, the 24 Tradecraft ones 400,590 EXP and the 27 Grand Company ones 205,186 EXP, which puts this leve 31% below its own category's average.
Nothing on the turn-in list is craftable in this data: Blue Cloud Coral ×3 has no recipe here, so 3 units must come from gathering, a vendor or a drop.
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 1,949,565 EXP and 1,170 gil for the 1 allowance it costs, or 1,949,565 EXP per allowance.
