Mythic+ Season 3 The War Within 11.2
Last updated: October 7, 2025

These statistics show the current WoW Meta in The War Within, using daily-updated data from the Official Blizzard Mythic+ API.

📖 Explanation
  • LB_CI: Lower bound of a 95% confidence interval, calculated on the full dataset. This metric is chosen because it provides a conservative estimate of player performance, accounting for variability in the data.
  • MEAN: Calculated by summing all values and dividing by N, representing the average performance metric across all players.
  • MAX: Maximum value of the metric, indicating the highest performance achieved in the dataset.
  • N: Number of players in the dataset, providing the sample size for statistical calculations.
  • Score: Official Blizzard Mythic+ Score from the API, reflecting the performance rating as determined by Blizzard's metrics.

Tiers are formed by distributing specs using the Ckmeans algorithm, which is chosen for its optimal one-dimensional clustering capabilities. Specs are binned in clusters (tiers) based on the LB_CI value.

This algorithm is particularly effective for datasets where the goal is to create distinct, non-overlapping groups based on a single variable, in this case, the LB_CI value.

The algorithm ensures optimal and deterministic clustering results, meaning tier boundaries remain consistent when run multiple times with the same data. The number of clusters is 5: S, A, B, C, D, with each tier representing a different level of performance.
