Dappling the Highlands (L)

At 10 allowances a run, this leve's 427,710 EXP works out to 42,771 EXP per allowance, which places it 3rd of the 3 Lv 58 Alchemist Grand Company leves that record EXP. The best of them, A Gate Arcane Is Dragon's Bane (L), returns 446,249 EXP for the same allowance, 943% more.

Across that rung the return runs from 42,771 EXP to 446,249 EXP per allowance — 3 distinct figures spanning 943%, so the wrong pick leaves 403,478 EXP of the allowance unspent.

Nothing above Lv 58 is recorded for Alchemist Grand Company leves, so this rung is the ceiling at 446,249 EXP per allowance — 52% more than the Lv 56 rung below it.

At Lv 58 this data holds 54 leves paying EXP across 3 categories: the 27 Grand Company ones average 228,371 EXP per allowance, the 3 Fieldcraft ones 1,079,567 EXP and the 24 Tradecraft ones 443,090 EXP, which puts this leve 81% below its own category's average.

Growth Formula Zeta ×1 is a Lv 58 Alchemist recipe, a single step, costing 6 units of raw material and 5 crystals.

Handing that in returns 71,285 EXP and 234 gil for every unit of raw material the order swallows.

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 2,566,260 EXP and 8,424 gil for the 10 allowances it costs, or 256,626 EXP per allowance.
