The KTRENZ Hype Index (0–100) blends up to five live signals — KTRENZ editorial coverage momentum over the last 30 days (25%), AI-retrieval attention on the artist (20%), upcoming scheduled activity (15%), external demand from Naver search and YouTube traction (25%), and third-party SNS posts anchored to the act’s releases in the last 30 days (15%) — each log-normalized against a fixed cap. The first three exist for every act. The last two require data we do not have for everyone: where a signal is not measured it is left out and the remaining weights are renormalized, so an act is never scored down for something we simply did not observe.
