This page provides a song-wise scale reference for both SP and DP charts. Each table lists the chart title, difficulty label, discrimination, and the estimated EASY and HARD clear difficulty values.
Discrimination: how strongly a chart separates player skill levels.
Easy: estimated difficulty for achieving an EASY clear.
Hard: estimated difficulty for achieving a HARD clear.
Rows marked with a ⚠ badge are low-confidence estimates (small sample, or success/fail counts too one-sided to pin the difficulty) — treat their numbers as provisional.
Rows tagged NEW did not exist in the previous published update.
↑ / ↓ next to a number shows how that value moved compared to the previously published estimate (hover for exact before → after).
These values are only rough analytical references, so please do not treat them as absolute or fully reliable ratings.
