Snail Fail

One allowance here buys 549,769 EXP, which places it 3rd of the 4 Lv 45 Fisher fieldcraft leves that record EXP — a figure 1 other leve on the rung matches exactly. The best of them, Putting the Zap on Nature, returns 916,282 EXP for the same allowance, 67% more.

On whether to wait: the best Lv 50 Fisher fieldcraft leve returns 963,302 EXP per allowance, 5% more than the best on this rung, while the Lv 40 rung behind tops out at 700,265 EXP.

At Lv 45 this data holds 52 leves paying EXP across 2 categories: the 4 Fieldcraft ones average 733,026 EXP per allowance, the 48 Tradecraft ones 98,250 EXP, which puts this leve 25% below its own category's average.

Nothing on the turn-in list is craftable in this data: Ignus Snail ×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 1,649,307 EXP and 879 gil for the 1 allowance it costs, or 1,649,307 EXP per allowance.
