What the allowance actually buys
One allowance here buys 2,459,716 EXP — the identical figure every one of the 2 Lv 80 Fisher fieldcraft leves pays, so on this rung the turn-in and the walk are the only things that actually differ.
On whether to wait: the best Lv 82 Fisher fieldcraft leve returns 2,464,410 EXP per allowance, 0% more than the best on this rung, while the Lv 78 rung behind tops out at 2,456,744 EXP.
At Lv 80 this data holds 18 leves paying EXP across 2 categories: the 2 Fieldcraft ones average 2,459,716 EXP per allowance, the 16 Tradecraft ones 854,332 EXP, which puts this leve 0% above its own category's average.
Nothing on the turn-in list is craftable in this data: Ruby-spotted Crab ×9 has no recipe here, so 9 units must come from gathering, a vendor or a drop.
Onokoro, The Ruby Sea issues 13 leves in this dataset, Lv 62 through Lv 84, across 3 disciplines.
