What the allowance actually buys
One allowance here buys 153,202 EXP, which places it 3rd of the 4 Lv 25 Fisher fieldcraft leves that record EXP — a figure 1 other leve on the rung matches exactly. The best of them, A Shocking Soirée, returns 255,336 EXP for the same allowance, 67% more.
On whether to wait: the best Lv 30 Fisher fieldcraft leve returns 344,153 EXP per allowance, 35% more than the best on this rung, while the Lv 20 rung behind tops out at 141,630 EXP.
At Lv 25 this data holds 52 leves paying EXP across 2 categories: the 4 Fieldcraft ones average 204,269 EXP per allowance, the 48 Tradecraft ones 31,772 EXP, which puts this leve 25% below its own category's average.
Nothing on the turn-in list is craftable in this data: Dark Bass ×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 459,606 EXP and 489 gil for the 1 allowance it costs, or 459,606 EXP per allowance.
