What the allowance actually buys
One allowance here buys 379,930 EXP, the best of the 6 Lv 56 Goldsmith tradecraft leves that record EXP: the runner-up manages 240,180 EXP, 37% less.
Across that rung the return runs from 63,322 EXP to 379,930 EXP per allowance — 5 distinct figures spanning 500%, so the wrong pick leaves 316,608 EXP of the allowance unspent.
On whether to wait: the best Lv 58 Goldsmith tradecraft leve returns 427,710 EXP per allowance, 13% more than the best on this rung, while the Lv 54 rung behind tops out at 647,060 EXP.
At Lv 56 this data holds 54 leves paying EXP across 2 categories: the 48 Tradecraft ones average 284,330 EXP per allowance, the 6 Fieldcraft ones 684,949 EXP, which puts this leve 34% above its own category's average.
Gil ranks it differently: 383 gil per allowance is 5th of 6 on the same rung against 1st on EXP, with the best there paying 998 gil.
Hardsilver Planisphere ×1 is a Lv 57 Goldsmith recipe, 3 steps deep through 8 intermediates, costing 48 units of raw material and 55 crystals.
Handing that in returns 7,915 EXP and 8 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Blacksmith and Goldsmith.
