FAQ

What is Kikoku worth in GPO?

Kikoku's current trading value is approximately 19K (range 17K–21K), based on 2,464 observed Discord trades over the last solver run. Updated 2026-06-02.

How is the value calculated?

Values are derived from observed Discord trade messages using a ratio-chain solver against the anchor item. No editor opinions, no hand-tuned numbers. See /legal/methodology for the full math.

Why is the value a range, not one number?

The range is a 90% confidence band. The single headline number is the median; the band shows where the solver thinks the true value lives given noise.

Is Kikoku's demand Low forever?

No. Demand is recomputed every solver run from the offered:wanted ratio in trade messages. Kikoku's current ratio is 0.82 (1,107 wanted vs 1,357 offered) — that's why demand is Low right now.
