What the allowance actually buys
One allowance here buys 1,474,046 EXP, which places it 3rd of the 3 Lv 78 Fisher fieldcraft leves that record EXP. The best of them, Short-term Gains, returns 2,456,744 EXP for the same allowance, 67% more.
On whether to wait: the best Lv 80 Fisher fieldcraft leve returns 2,459,716 EXP per allowance, 0% more than the best on this rung, while the Lv 76 rung behind tops out at 2,091,086 EXP.
At Lv 78 this data holds 27 leves paying EXP across 2 categories: the 3 Fieldcraft ones average 2,129,178 EXP per allowance, the 24 Tradecraft ones 955,432 EXP, which puts this leve 31% below its own category's average.
Nothing on the turn-in list is craftable in this data: Stippled Eel ×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 4,422,138 EXP and 2,340 gil for the 1 allowance it costs, or 4,422,138 EXP per allowance.
