DDR A3 Scoring Difficulty Tier List

The DDR A3 Scoring Difficulty Tier List powered by Skill Attack, showcases songs and charts’ comparative difficulties to one another within the same difficulty level. Songs with a certain level are broken down into different tiers, marked from X.00 to X.99 (X.0 to X.9 for Level 19). The higher the song is in a tier, the harder it is to score on. Score data is taken from Skill Attack, an online DDR score tracker. Using various formulas and thresholds, each song is given a value (called an SA value) to determine its overall scoring difficulty. Building off the A20 and A20 PLUS lists, the A3 lists has brand new features. A differential counter is now used to show the change in a song’s SA value compared to the previous list. Most importantly, a percentage skew has been added to newer songs’ score counts to prevent recency bias, which has historically shown to place newer songs lower than usual in their tier lists.
