One allowance here buys 226,120 EXP, which places it 3rd of the 3 Lv 62 Blacksmith tradecraft leves that record EXP. The best of them, Crisscrossing, returns 705,130 EXP for the same allowance, 212% more.

Across that rung the return runs from 226,120 EXP to 705,130 EXP per allowance — 3 distinct figures spanning 212%, so the wrong pick leaves 479,010 EXP of the allowance unspent.

On whether to wait: the best Lv 64 Blacksmith tradecraft leve returns 489,060 EXP per allowance, 31% less than the best on this rung, while the Lv 60 rung behind tops out at 703,720 EXP.

At Lv 62 this data holds 27 leves paying EXP across 2 categories: the 24 Tradecraft ones average 417,590 EXP per allowance, the 3 Fieldcraft ones 1,118,055 EXP, which puts this leve 46% below its own category's average.

High Steel File ×1 is a Lv 62 Blacksmith recipe, 3 steps deep through 4 intermediates, costing 22 units of raw material and 21 crystals.

Handing that in returns 10,278 EXP and 45 gil for every unit of raw material the order swallows, and the tree needs Blacksmith and Weaver.

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 678,360 EXP and 2,973 gil for the 1 allowance it costs, or 678,360 EXP per allowance.
