What the allowance actually buys
One allowance here buys 2,091,086 EXP, the best on the Lv 76 Fisher fieldcraft rung — matched exactly by 1 other leve of the 3 there, with the rest trailing at 1,254,652 EXP or less.
On whether to wait: the best Lv 78 Fisher fieldcraft leve returns 2,456,744 EXP per allowance, 17% more than the best on this rung, while the Lv 74 rung behind tops out at 1,816,458 EXP.
At Lv 76 this data holds 27 leves paying EXP across 2 categories: the 3 Fieldcraft ones average 1,812,275 EXP per allowance, the 24 Tradecraft ones 754,791 EXP, which puts this leve 15% above its own category's average.
Nothing on the turn-in list is craftable in this data: Gourmand Crab ×9 has no recipe here, so 9 units must come from gathering, a vendor or a drop.
The Crystarium issues 165 leves in this dataset, Lv 70 through Lv 78, across 11 disciplines.
