What the allowance actually buys
One allowance here buys 84,978 EXP, which places it 3rd of the 4 Lv 20 Fisher fieldcraft leves that record EXP — a figure 1 other leve on the rung matches exactly. The best of them, Sounds Fishy to Me, returns 141,630 EXP for the same allowance, 67% more.
On whether to wait: the best Lv 25 Fisher fieldcraft leve returns 255,336 EXP per allowance, 80% more than the best on this rung, while the Lv 15 rung behind tops out at 98,039 EXP.
At Lv 20 this data holds 52 leves paying EXP across 2 categories: the 4 Fieldcraft ones average 113,304 EXP per allowance, the 48 Tradecraft ones 17,352 EXP, which puts this leve 25% below its own category's average.
Nothing on the turn-in list is craftable in this data: Faerie 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 254,934 EXP and 390 gil for the 1 allowance it costs, or 254,934 EXP per allowance.
