The Road Was a Ribbon of Moonlight (L)

At 10 allowances a run, this leve's 272,720 EXP works out to 27,272 EXP per allowance, which places it 6th of the 6 Lv 50 Weaver tradecraft leves that record EXP. The best of them, Pride Up in Smoke, returns 211,350 EXP for the same allowance, 675% more.

Across that rung the return runs from 27,272 EXP to 211,350 EXP per allowance — 5 distinct figures spanning 675%, so the wrong pick leaves 184,078 EXP of the allowance unspent.

On whether to wait: the best Lv 52 Weaver tradecraft leve returns 480,670 EXP per allowance, 127% more than the best on this rung, while the Lv 45 rung behind tops out at 199,230 EXP.

At Lv 50 this data holds 54 leves paying EXP across 2 categories: the 48 Tradecraft ones average 176,840 EXP per allowance, the 6 Fieldcraft ones 553,899 EXP, which puts this leve 85% below its own category's average.

Rainbow Ribbon of Healing ×1 is a Lv 51 Weaver recipe, 3 steps deep through 5 intermediates, costing 21 units of raw material and 21 crystals.

Handing that in returns 12,987 EXP and 41 gil for every unit of raw material the order swallows, and the tree needs Goldsmith and Weaver.

The record carries a repeats value of 5. This site reads that as 5 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 1,636,320 EXP and 5,148 gil for the 10 allowances it costs, or 163,632 EXP per allowance.
